Pelangi merupakan suatu busur spekt

Pelangi merupakan suatu busur spektrum besar yang terjadi karena pembiasan cahaya matahari oleh butir-butir air. Pelangi 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.


Biasanya fenomena ini terjadi ketika udara sangat panas tetapi hujan turun rintik-rintik. Kita dapat melihat jelas fenomena ini, jika kita berdiri membelakangi cahaya matahari. Pelangi dapat pula terbentuk karena udara berkabut atau berembun.


Dalam ilmu fisika, pelangi dapat dijelaskan sebagai sebuah peristiwa pembiasan alam. Pembiasan merupakan proses diuraikannya satu warna tertentu menjadi beberapa warna lainnya (disebut juga spektrum warna), melalui suatu media/ medium tertentu pula.


Pada pelangi, proses berurainya warna terjadi ketika cahaya matahari yang berwarna putih terurai menjadi spektrum warna melalui media air hujan. Adapun spektrum warna yang terjadi terdiri atas warna merah, jingga, kuning, hijau, biru, nila, dan ungu.


Fenomena pelangi dapat pula terjadi di sekitar air terjun. Percikan air di sekitar air terjun menjadi media untuk menguraikan warna dari cahaya matahari yang bersinar.


Proses Terjadinya 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 ungu.


Panjang gelombang cahaya ini membentuk pita garis-garis paralel, tiap warna bernuansa dengan warna di sebelahnya. Pita ini disebut spektrum. Di dalam spektrum, garis merah selalu berada pada salah satu sisi dan biru serta ungu di sisi lain, dan ini ditentukan oleh perbedaan panjang gelombang.

The Rainbow is a large spectrum of arc occurs due to refraction of light of the Sun by a grain of water. A rainbow is an optical and meteorological phenomena in the form of colourful interlocking parallel light appears in the sky or other medium. Rainbow in the sky, looked as the light arc with its end point on the horizon at a time of light rain. Rainbows can also be seen around the waterfall Rapids.


Usually this phenomenon occurs when the air is very hot but light rain fell. We can see clearly this phenomenon, if we stand backs onto the light from the Sun. Rainbows may also form due to the foggy air or dewy.


in physics, the rainbow can be explained as a natural refraction of events. Refraction is the process of diuraikannya a certain color to be some other color (also called color spectrum), through a specific medium/medium well.


At Rainbow, color berurainya process happens when sunlight is white in color spectrum decomposes to rainwater through the media. As for the spectrum of colors which occur consists of red, Orange, yellow, green, Blue, Indigo, and violet.


Rainbow Phenomenon can also occur around the waterfall. Sprinkling water around the waterfall into a medium for describing colors of light from the Sun that shines.





full Rainbow Process sunlight is light polikromatik (made up of many colors). White light from the Sun is actually a composite of various light with different wavelengths. The human eye is able to observed at least seven color contained light from the Sun, which will be seen in a rainbow: red, Orange, yellow, green, blue, Indigo, and violet.


wavelength of light forms a Ribbon of parallel lines, each colour nuances the colour next to it. This band is called the spectrum. In the spectrum, the red line is always on one side and blue and purple on the other hand, and this is determined by the difference of wavelength.

Spectrum of the rainbow is a big arc that occurs due to the refraction of sunlight by water beads. Rainbow is an optical and meteorological phenomenon in the form of multi-colored light that seems parallel to each other in the sky or other medium. In the sky, a rainbow appears as an arc light with a tip leads to the horizon in a light rain. Rainbow can also be seen around a raging waterfall. Usually this phenomenon occurs when the air is very hot but the rain drizzle down. We can see this phenomenon clearly, if we stood against the light of the sun. Rainbow can also be formed because the air is foggy or frosted. In physics, a rainbow can be explained as a natural refraction event. Refraction is the process diuraikannya one specific color into another color (also called the color spectrum), through a medium / medium are also given. At the rainbow, color berurainya process occurs when white sunlight breaks down into a spectrum of colors through the medium of the rain water. The spectrum of colors that occur consist of red, orange, yellow, green, blue, indigo, and violet. phenomenon can also occur in a rainbow around the waterfall. Splash water around the falls into the media to decipher the color of sunlight that shines. process of occurrence of rainbow light sunlight is polychromatic (consists of many colors). White sunlight is actually a combination of various wavelengths of light different. The human eye is capable of perceiving at least seven colors contained in sunlight, which will look at the rainbow: red, orange, yellow, green, blue, indigo, and violet. wavelength band of light formed parallel lines, each color with shades of color next. This tape is called a spectrum. In the spectrum, the red line has always been on one side and blue and purple on the other hand, and this is determined by the wavelength difference.
