# NEET Physics Ray Optics and Optical Instruments Questions Solved

A ray of light is incident at an angle of incidence, i, on one face of a prism of angle A (assumed to be small) and emerges normally from the opposite face.If the refractive index of the prism is $\mu ,$ the angle of incidence i, is nearly equal to

(a)$\mu A$                                    (b)$\frac{\mu A}{2}$

(c)$A/\mu$                                  (d)$A/2\mu$
