Experiment to Show the Recomposition of White Light
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..

Dispersion..Dispersion of White Light By a Glass Prism
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..
