Question

define angular dispertions for a prism obtain is expression for a thin prism relate it with the refractive indices of the materials of the prism for corresponding colors ​

Answer 1

Explanation:

The sum of these two deflections is called the deviation angle. The deviation angle in a prism depends upon: Refractive index of the prism: The refractive index depends on the material and the wavelength of the light. ... The deviation angle first increases with increasing incidence angle, and then decreases.
