Question

How does the deviation produced by a prism depend on (i) the frefractive index of its material, and (ii) the wavelength of incident light.

Answer 1

The deviation angle in a prism depends upon:

i. Refractive index of the prism: The refractive index depends on the material and the wavelength of the light. The larger the refractive index, the larger the deviation angle.

ii. Angle of the prism: The larger the prism angle, the larger the deviation angle.
