dispersion of light rainbow

It is the natural spectrum of the sun's light when they fall on raindrops during or after a shower. ..

Sir Isaac Newton, while studying the images of heavenly bodies formed by a lens, found that the image is colored at its edges. In 1665, to investigate this, he performed an experiment using a prism. Newton darkened his room at Trinity College, Cambridge and allowed a beam of sunlight to pass throug..

It is the phenomenon of splitting of a beam of white light into its constituent colors on passing through prism. The order of colors from the lower end are violet, indigo, blue, green, yellow, orange and re..

The small droplets of rain water which remain suspended in air just after the rains act like a prism. When sunlight passes through these drops of rainwater, it gets dispersed and we see the seven colors of the rainbow..

It is a matter of common experience that precious stones like diamonds, rubies, etc. or glass pieces glitter when light, particularly white light is incident on it. In this chapter let us find out why white light incident on a transparent prism splits into differ..

Even though all colours of the visible spectrum travel with the same speed in vacuum, the speed of the colours of the visible spectrum varies when they pass through a transparent medium like glass and water. That is, the refractive index of glass is different for different colours. When a poly..
