Question

Snell's Law Example Problem A laser beam in air is incident on a liquid at an angle of 37.0° with respect to the normal. The laser beam's angle in the liquid is 26.0°. What is the liquid's index of refraction?

Answer 1

Here,

i = 37 degree

r = 26 degree

let the refractive index of liquid is n

Using snell's law

1 * sin(i) = n * sin(r)

1 * sin(37 degree) = n * sin(26 degree)

n = 1.37

the index of refraction is 1.37
