Vedclass · Answer

(C) Dispersion is the phenomenon of splitting of white light into its constituent colours.In a medium like glass, the refractive index $(n)$ depends on the wavelength $(\lambda)$ of the light, a property known as dispersion.The speed of light in a medium is given by $v = c/n$.Since different colours (wavelengths) have different refractive indices in the flint glass, they travel at different speeds $(v)$ within the prism.This difference in speed leads to different angles of deviation for each colour, causing the light to disperse.Therefore, the correct reason is that light of different colours travels with different speeds in the glass medium.

We use a flint glass prism to disperse polychromatic light because light of different colours:
