Rainbow is one of optic phenomena that happens in the atmosphere of the earth naturally. We can see it at Arainbow is formed because white light enters the water droplet, where it bends in several different directions. When these bent light waves reach the other side of the water droplet, they reflect back out of the droplet instead of completely traversing the water.

Dear Readers, “Everybody wants happiness, nobody wants pain, but you can’t have a RAINBOW without a little rain.” Pelangi atau bianglala adalah gejala optik dan meteorologi berupa cahaya beraneka warna saling sejajar yang tampak di langit atau medium lainnya. Di langit, pelangi tampak sebagai busur cahaya dengan ujungnya mengarah pada horizon pada suatu saat hujan ringan. Pelangi juga dapat dilihat di sekitar air terjun yang deras. – Artikel hari ini berisi tentang Explanation Text About RAINBOW Lengkap dengan Terjemahan dan Pembahasan Materi.

Explanation Text About RAINBOW Lengkap dengan Terjemahan dan Pembahasan MateriExplanation TextRAINBOWTerjemahanPembahasan Materi Explanation Text RAINBOW Sunlight is a polychromatic light consisting of many colors. The white color of sunlight is actually a combination of various light with different wavelengths. The human eye is able to perceive at least seven colors of sunlight, which will be seen in the rainbow red, orange, yellow, green, blue, indigo and violet. This wavelength of light forms a ribbon of parallel lines, each nuanced color with a color next to it. This band is called the color spectrum. In the color spectrum, the red lines are always on one side and blue and violet on the other, and this is determined by the difference in wavelength. Rainbow is a natural phenomenon that is so impressive. This phenomenon often appears after rain. Rainbow is an arc spectrum which is so large and occurs because the drops are refracted by sunlight. When the sun is shining and the light passing through water droplets, then you will see a refraction that causes a wide variety of colors. Light is refracted like light passing through a glass prism. How does rainbow happen in detail? All the happenings begin when the sunlight passing through the raindrops. Then the light is deflected to the center of the droplet. The white light, now separated from each other into a spectrum of colors. The process does not stop there. The colors that have been separated, then separate again into the very small portions. There is more light separated from each other in the droplets. Then there are more curved and finally those color form a light curve called a rainbow. Rainbow is nothing but an arc of a large circular spectrum of color that occurs due to refraction of sunlight by water grains. When sunlight passes through water droplets, it refracts like when it penetrates a glass prism and comes out into a rainbow color spectrum. So inside the water droplets, we have got different colors lined up from one side to the other. Some of this colored light is then reflected from the far side of the water droplets, returning and exiting again from the water droplets. Light comes back from water droplets in a different direction, depending on the color. The colors on this rainbow are arranged in red at the top and purple at the bottom of the rainbow. Rainbow is seen as a bow from the surface of the earth because of the limited viewing angle of the eye, if the vantage point in a high place, for example from an airplane, can be seen as a complete color spectrum in the form of a circle. The rainbow can only be seen when it rains together with the sun shining but from the opposite side of the observer. The position of the observer must be between the sun and the droplets of water with the sun behind the person. The sun, the eye of the observer, and the center of the rainbow arc must be in a straight line. Can we make a rainbow? Of course. There are at least two ways that you can do to make a rainbow. First, you can use a spray containing water. We know that rainbows occur when sunlight passing through the raindrops. So, we make our own rain droplets from the water spray. In the morning or afternoon, spray water under the sun, then see the water droplets flying. Spray lots of water and you will see a small rainbow that you can touch easily. Second, use pieces of video discs then reflected the light of the sun, and navigate to the wall or ceiling of your house. On the ceiling or the wall, you will see a colorful light that has the same color as the rainbow. That’s the definition of rainbow, how does it happen, and how we can make it true. Terjemahan PELANGI Cahaya matahari adalah cahaya polikromatik terdiri dari banyak warna. Warna putih cahaya matahari sebenarnya adalah gabungan dari berbagai cahaya dengan panjang gelombang yang berbeda-beda. Mata manusia sanggup mencerap paling tidak tujuh warna yang dikandung cahaya matahari, yang akan terlihat pada pelangi merah, jingga, kuning, hijau, biru, nila, dan violet. Panjang gelombang cahaya ini membentuk pita garis-garis paralel, tiap warna bernuansa dengan warna di sebelahnya. Pita ini disebut spektrum warna. Di dalam spektrum warna, garis merah selalu berada pada salah satu sisi dan biru serta violet di sisi lain, dan ini ditentukan oleh perbedaan panjang gelombang. Pelangi adalah sebuah fenomena alam yang begitu mengesankan. Fenomena ini sering muncul setelah hujan. Pelangi merupakan sebuah busur spektrum yang begitu besar dan terjadi karena butir-butir air yang dibiaskan oleh cahaya matahari. Ketika cahaya matahari tersebut bersinar dan melewati butiran air, maka Anda akan menyaksikan sebuah pembiasan yang menyebabkan timbulnya berbagai macam warna. Cahaya tersebut membias layaknya sebuah cahaya yang melewati prisma kaca. Bagaimana proses terjadinya pelangi secara detail? Semua kejadian dimulai ketika cahaya matahari melewati tetesan hujan. Kemudian cahaya tersebut dibelokkan ke bagian tengah dari tetesan tersebut. Cahaya yang sebelumnya putih, kini saling terpisah menjadi sebuah warna spektrum. Prosesnya tidak berhenti hanya disitu saja. Warna-warna yang telah terpisah, kemudian terpisah kembali hingga ke bagian-bagian yang sangat kecil. Ada lebih banyak cahaya yang terpisah satu sama lain di tetesan-tetesan tersebut. Semakin lama, cahaya semakin melengkung dan membentuk kurva yang disebut dengan pelangi. Pelangi tidak lain adalah busur spektrum warna besar berbentuk lingkaran yang terjadi karena pembiasan cahaya matahari oleh butir-butir air. Ketika cahaya matahari melewati butiran air, ia membias seperti ketika menembus prisma kaca dan keluar menjadi spektrum warna pelangi. Jadi di dalam tetesan air, kita sudah mendapatkan warna yang berbeda-beda berderet dari satu sisi ke sisi tetesan air lainnya. Beberapa dari cahaya berwarna ini kemudian dipantulkan dari sisi yang jauh pada tetesan air, kembali dan keluar lagi dari tetesan air. Cahaya keluar kembali dari tetesan air ke arah yang berbeda, tergantung pada warnanya. Warna-warna pada pelangi ini tersusun dengan merah di paling atas dan ungu di paling bawah pelangi. Pelangi terlihat sebagai busur dari permukaan bumi karena terbatasnya sudut pandang mata, jika titik pandang di tempat yang tinggi misalnya dari pesawat terbang dapat terlihat sebagai spektrum warna yang lengkap yaitu berbentuk lingkaran. Pelangi hanya dapat dilihat saat hujan bersamaan dengan matahari bersinar, tetapi dari sisi yang berlawanan dengan si pengamat. Posisi si pengamat harus berada di antara matahari dan tetesan air dengan matahari di belakang orang tersebut. Matahari, mata si pengamat, dan pusat busur pelangi harus berada dalam satu garis lurus. Apakah kita bisa membuat pelangi? Tentu saja. Setidaknya ada tiga cara yang bisa Anda lakukan untuk membuat sebuah pelangi. Pertama, Anda bisa menggunakan semprotan yang berisi air. Kita tahu bahwa pelangi terjadi ketika cahaya matahari melewati tetesan hujan. Jadi, tetesan hujan kita buat sendiri dari semprotan air tersebut. Ketika pagi atau sore, semprotkan air di bagian bawah sinar matahari, kemudian lihat tetesan air yang beterbangan. Semprotkan banyak air dan kamu akan melihat sebuah pelangi kecil yang bisa kamu sentuh. Kedua, gunakan kepingan video disc kemudian pantulkan ke arah cahaya matahari dan arahkan ke dinding atau plafon rumahmu. Di plafon atau dinding tersebut, kamu akan melihat sebuah cahaya warna-warni yang mempunyai warna sama dengan pelangi. Itulah definisi mengenai pelangi, bagaimana itu terjadi, dan bagaimana kita mampu membuatnya.

A rainbow is an excellent demonstration of the dispersion of light and one more piece of evidence that visible light is composed of a spectrum of wavelengths, each associated with a distinct color. To view a rainbow, your back must be to the sun as you look at an approximately 40 degree angle above the ground into a region of the atmosphere with suspended droplets of water or even a light mist. Each individual droplet of water acts as a tiny prism that both disperses the light and reflects it back to your eye. As you sight into the sky, wavelengths of light associated with a specific color arrive at your eye from the collection of droplets. The net effect of the vast array of droplets is that a circular arc of ROYGBIV is seen across the sky. But just exactly how do the droplets of water disperse and reflect the light? And why does the pattern always appear as ROYGBIV from top to bottom? These are the questions that we will seek to understand on this page of The Physics Classroom Tutorial. To understand these questions, we will need to draw upon our understanding of refraction, internal reflection and dispersion. The Path of Light Through a Droplet A collection of suspended water droplets in the atmosphere serves as a refractor of light. The water represents a medium with a different optical density than the surrounding air. Light waves refract when they cross over the boundary from one medium to another. The decrease in speed upon entry of light into a water droplet causes a bending of the path of light towards the normal. And upon exiting the droplet, light speeds up and bends away from the normal. The droplet causes a deviation in the path of light as it enters and exits the drop. There are countless paths by which light rays from the sun can pass through a drop. Each path is characterized by this bending towards and away from the normal. One path of great significance in the discussion of rainbows is the path in which light refracts into the droplet, internally reflects, and then refracts out of the droplet. The diagram at the right depicts such a path. A light ray from the sun enters the droplet with a slight downward trajectory. Upon refracting twice and reflecting once, the light ray is dispersed and bent downward towards an observer on earth's surface. Other entry locations into the droplet may result in similar paths or even in light continuing through the droplet and out the opposite side without significant internal reflection. But for the entry location shown in the diagram at the right, there is an optimal concentration of light exiting the airborne droplet at an angle towards the ground. As in the case of the refraction of light through prisms with nonparallel sides, the refraction of light at two boundaries of the droplet results in the dispersion of light into a spectrum of colors. The shorter wavelength blue and violet light refract a slightly greater amount than the longer wavelength red light. Since the boundaries are not parallel to each other, the double refraction results in a distinct separation of the sunlight into its component colors. The angle of deviation between the incoming light rays from the sun and the refracted rays directed to the observer's eyes is approximately 42 degrees for the red light. Because of the tendency of shorter wavelength blue light to refract more than red light, its angle of deviation from the original sun rays is approximately 40 degrees. As shown in the diagram, the red light refracts out of the droplet at a steeper angle toward an observer on the ground. There are a multitude of paths by which the original ray can pass through a droplet and subsequently angle towards the ground. Some of the paths are dependent upon which part of the droplet the incident rays contact. Other paths are dependent upon the location of the sun in the sky and the subsequent trajectory of the incoming rays towards the droplet. Yet the greatest concentration of outgoing rays is found at these 40-42 degree angles of deviation. At these angles, the dispersed light is bright enough to result in a rainbow display in the sky. Now that we understand the path of light through an individual droplet, we can approach the topic of how the rainbow forms. The Formation of the Rainbow A rainbow is most often viewed as a circular arc in the sky. An observer on the ground observes a half-circle of color with red being the color perceived on the outside or top of the bow. Those who are fortunate enough to have seen a rainbow from an airplane in the sky may know that a rainbow can actually be a complete circle. Observers on the ground only view the top half of the circle since the bottom half of the circular arc is prevented by the presence of the ground and the rather obvious fact that suspended water droplets aren't present below ground. Yet observers in an airborne plane can often look both upward and downward to view the complete circular bow. The circle or half-circle results because there are a collection of suspended droplets in the atmosphere that are capable concentrating the dispersed light at angles of deviation of 40-42 degrees relative to the original path of light from the sun. These droplets actually form a circular arc, with each droplet within the arc dispersing light and reflecting it back towards the observer. Every droplet within the arc is refracting and dispersing the entire visible light spectrum ROYGBIV. As described above, the red light is refracted out of a droplet at steeper angles towards the ground than the blue light. Thus, when an observer sights at a steeper angle with respect to the ground, droplets of water within this line of sight are refracting the red light to the observer's eye. The blue light from these same droplets is directed at a less steep angle and is directed along a trajectory that passes over the observer's head. Thus, it is the red light that is seen when looking at the steeper angles relative to the ground. Similarly, when sighting at less steep angles, droplets of water within this line of sight are directing blue light to the observer's eye while the red light is directed downwards at a more steep angle towards the observer's feet. This discussion explains why it is the red light that is observed at the top and on the outer perimeter of a rainbow and the blue light that is observed on the bottom and the inner perimeter of the rainbow. Rainbows are not limited to the dispersion of light by raindrops. The splashing of water at the base of a waterfall caused a mist of water in the air that often results in the formation of rainbows. A backyard water sprinkler is another common source of a rainbow. Bright sunlight, suspended droplets of water and the proper angle of sighting are the three necessary components for viewing one of nature's most splendid masterpieces.

By Published Aug 9, 2021 1244 PM EDT To see how rainbows are formed, try a simple experiment. Go outside during a sun-drenched rain and look out toward the storm. Deposit Photos Thisspost has been updated. It published on January 8, 2019. Because of their colorful and unique display, rainbows have generated countless legends and myths throughout history. Among the most popular is the Irish folklore that leprechauns store their pot of gold at the end of a rainbow. But the truth is, rainbows can be seen only if you are in the right place at the right time. If you’ve ever seen one, consider yourself lucky. For the magical band of the colors to appear, the conditions must be just right. Which leads us to the question, how are rainbows formed exactly? Rainbows can be seen when light passes through raindrops, says Kristin Calhoun, a research scientist at the National Oceanic & Atmospheric Administration NOAA, the scientific agency focusing in part on the conditions of weather. When a person sees a rainbow, it’s really an optical illusion created by the refraction and reflection of light. An optical illusion is when you see something that appears to be something other than what is really there. When sunlight passes through raindrops, the light bends, or refracts, as it enters the droplet, and then reflects off the inside of the raindrop. This happens because the water is more dense than the air that surrounds it. As it exits the droplet, the light separates into wavelengths. Visible light is made up of various wavelengths, and each wavelength appears as a different color red, orange, yellow, green, blue, indigo and violet. Red light, for example, bends at a different angle than violet light. This is why “the person on the ground sees each color at a different location,” Calhoun says, and why rainbows look like a bow or an arc. Sometimes, however, rainbows can actually form an entire circle that you can see in a plane with the right conditions. [Related What causes a rainbow at night?] Because rainbows are created by light via raindrops, the best time to catch a rainbow is when it’s sunny and raining. “There is an even better chance when the sun is at a lower angle, so early or later in the day,” Calhoun says. If you’re trying to spot one, the key is to face the rain and have your back to the sun. With the conditions just right, Hawaii gets lots of rainbows. “Small showers and storms often form in late afternoon due to the combined effects of topography and daytime heating of the land,” Calhoun says. “These types [of] showers often produce heavy rain, but remain isolated over the center of the island.” Because rainbows are optical illusions, they’re not located at a specific distance. The location is relative to the person. That means there’s no chance you’ll ever find that pot of gold.
