Question

what will be the lateral shift (in meter) in a light ray if the light ray is incident on a slab on 9 m thickness at an angle of incidence 60. refractive index of the material of the slab is 3

Answer 1

A ray of light is incident on the surface of a glass plate of thickness t. if the angle of incidence a is small, the emerging ray would be displaced sideways by an amount=?(let n be the refractive index of glass)
