Question

A ray of light from air is incident on a liquid surface at an angle of incidence 35°, calculate the angle of refraction if refractive index of liquid is 1.25

Answer 1

Answer:

27.402

Explanation:

formula;

sin r = (n1/n2)sin i.

r is the angle of refraction

i is the angle of incident

n1 is the refractive index of air=1.0003

n2 is the refractive index of liquid=1.25

by putting values in formula we get answer
