How The Process Of The Rainbow

How the process begins when the rainbow is sunlight passing through a drop of rain which then deflected or refracted toward the middle of the rain drops, which separates white light into a spectrum of colors. Then, separate colors is bouncing back and split drops of rain even more time left. As a result, the light appears to be curved curve known as rainbow colors. Light with the shortest wavelengths like violet, located on the curve and which has the longest wavelengths as there are red on the outside.

In the 17th century, the English scientist, Isaac Newton, (1642 -1727) discovered that white light is actually a mix of sun light of various colors. He shined a little sunlight through a triangular glass prism (glass blocks) in a dark room. The prism shape makes turning the light beam and then split into a wide band of light. In this tape, Newton saw seven colors called a spectrum. These colors are red, orange, yellow, green, blue, indigo and violet.

All light travels in waves. Is the wavelength of light determines the color. Sometimes, a second rainbow is fainter than the DAPT visible above the main pelagi because the light has been reflected or refracted more than once in the rain drops. Second rainbow colors were reversed, red and purple on the outside. The color is never as bright primary rainbow because each time the light is reflected, there is very little light is lost.

In 1852, German scientist, Ernst Von Brycke, stating that the blue color of the sky caused by particles in the atmosphere that scatter sunlight entering the atmosphere. Later, two British physicist, Lord Rayleigh (1842-1919) and John Tyndall (1820-1893) has another explanation. Rayleigh argued under the blue part of sunlight is spread by dust and water vapor, but he was wrong. Air molecules scatter light alone. Nevertheless we still refer to this as a kind penyeberan Tyndall effect, or the spread of Rayleigh, in accordance with both the name of the scientist.

Rainbow and other light effects in the sky caused by light refracted and distorted away from the particle. As the sun sets, the sky turned red because sunlight passing through the atmosphere is much thicker than when the sun is high in the sky at noon. Blue light is spread out the light path, and we saw the red wavelengths.
