Question

what are the factor on which angle of The deviation? depends

Answer 1

The deviation angle in a prism depends upon: Refractive index of the prism: The refractive index depends on thematerial and the wavelength of thelight. The larger the refractive index, the larger the deviation angle. Angle of the prism: The larger the prism angle, the larger the deviation angle.

Answer 2

denser and rarer medium when light passes from one medium to another medium it's velocity changes due to change in velocity a ray of light is deviated from its path when it falls on the surface of second medium obliquely
