Problem

A single ray traverses a glass plate (thickness

t

) with plane surfaces that are parallel to each other. The emergent ray is parallel to the incident ray but suffers a lateral displacement

d

. Assuming that glass plate (refractive index

\mu

) is placed in air, find the dependence of

d

on angle of incidence

i

. Plot the variation of

d

with

i

(changing from

0^\circ

90^\circ

)
