Hello! I'm having difficulty solving this problem, I was wondering if you can help me solve it.(adsbygoogle = window.adsbygoogle || []).push({});

Light is incident in air at an angle on the upper surface of a transparent plate, the surfaces of the plate being plane and parallel to each other.

A ray of light is incident at an angle of 66.0 on one surface of a glass plate 2.40 cm thick with an index of refraction 1.80. The medium on either side of the plate is air. Find the lateral displacement between the incident and emergent rays.

I know I am supposed to use the formula: n_1sin(theta_1) = n_2sin(theta_2)

index of refraction of air = 1.00

However I don't know how to approach this problem. I'm not asking for the answer, just maybe a few steps on how to approach this type of problem? And will I need to use trig to find the distance between the incident and emergent rays?

Thank you,

Sahar
