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 i..

Dispersion of Light - 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..

Place a prism (P 1 ) on a table and a screen behind it. Allow a narrow beam of light to be incident on the prism (P 1 ). The white light gets dispersed and we obtain a band of seven colours on the screen. Now remove the screen and place another prism P 2 of the s..

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..
