Question

A beam of light is emitted 7.6cm beneath the surface of a liquid and strikes the air surface 7.3cm from the point directly above the source.

Part A

If total internal reflection occurs, what can you say about the minimum possible index of refraction of the liquid?

apply the formula for apparant depth L = Lo/n

so here refractive index n = Lo/n

n = 7.6/7.3

n = 1.04 ----------<<<<<<<<<<<<<<Answer
