Question

A ray of light is incident at an angle of incidence i on one face

Answer 1

Answer:

A ray of light is incident at an angle of incidence, i, on one face of the prism of angle A (assumed to be small) and emerges normally from the opposite face.

If the refractive index of the prism is u, the angle of incidence i, is nearly equal to. A.

Answer 2

Answer:

A ray is incident at an angle of incidence i on one surface of a prism of small angle A and emerges normally from the opposite surface. If the refractive index of the material of prism is m, the angle of incidence
