All About Rainbw
One of nature's most splendid masterpieces is the rainbow. 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.
How is it formed?
Rainbows are formed because of the process of bending light knows as Refraction. different colors of light bend at different angles when they refract. When light from the sun enters a droplet of rain, it refracts a tiny bit causing the colors of light to spread apart, the light then bounces, or reflects, off of the back of the droppled and refracts once again as it leave the dropplet on the same side it entered. By the time the light reaches your eyes the refraction is so noticeable that you see all the colors of sunlight spread apart - creating a Rainbow
Colors of rb traditionally, the rainbow's colours are described as red, orange, yellow, green,blue, indigo and violet. In fact, our eyes can discern many more indivual hues. Rainbow colours are not "pure". The classical rainbow*, is made up of overlapping bows of individually pure spectral colours. The final colours that we see are mixtures. Any one colour of the bow has longer wavelength (towards red) colours mixed in.\ secondry rainbow
Secondary rainbows are caused by a double reflection of sunlight inside the raindrops, and appear at an angle of 50–53°. As a result of the second reflection, the colours of a secondary rainbow are inverted compared to the primary bow, with blue on the outside and red on the inside. The secondary rainbow is fainter than the primary because more light escapes from two reflections compared to
