Answer 1

Answer:

Heya

First the angle of deviation produced by prism decreases with the increasing angle of incidence but on further increasing the angle of incidence the angle of deviation increases. Figure given in side shows the graph for variation of angle of deviation with the angle of incidence.

Answer 2

The value of the angle of deviation produced by the prism deponds upon the angle of incidence , and the refractive index of the material . So refractive index depends upon on the wavelength and light . The larger the refractive index , larger is the angle of deviation . The deviation angle increases with increasing angle of incidence and then decreases...
