Dispersion of light

Vedclass · Answer

(A) When a beam of light passes through a medium,it undergoes refraction and deviates from its path. Different wavelengths of light travel at different speeds in a medium,causing them to bend by different angles. Shorter wavelengths (higher frequency) bend more than longer wavelengths. This separation of light into its constituent colors is known as dispersion,which results in the formation of a spectrum.

Explain the reason for the formation of a spectrum.
