Question

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)

Answer 1

Answer:

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 prismis μ, the angle of incidence i, is nearly equal to.
