Question

Maximum lateral displacement of a ray of light incident on a slab of thickness t is

Answer 1

Lateral displacement will be t/4

Answer 2

The lateral displacement of incident light ray depends upon two things when they emerge out of the media.

Those two things which determine or affect the lateral displacement of emergent ray are the thickness of the media for a particular angle at which incident ray strikes the surface along with the media pair it travels through, and incident angle for thickness of media and its pair. Therefore the lateral movement of light ray incident on slab with t thickness is t/4.
