Question

what is meaning of the dispersion of light

Answer 1

Visible light is actually made up of different colors. Each color bends by a different amount when refracted by glass. That's why visible light is split, or dispersed, into different colors when it passes through a lens or prism. Shorter wavelengths, like purple and blue light, bend the most. Longer wavelengths, like red and orange light, bend the least.

Answer 2

Dispersion of light means..it is the property by which light is spread out according to its color as it passes through an object. For example, when you shine a white light into a , all of the different colors of light are bent in different amounts, so they spread out and make a rainbow.
or in other words it simply means the scattering of light in different colours .
