Question

Monochromatic light has a wavelength of 2.85 × 10^7 m in air and 5.22 × 10^7 m in clear liquid. If the ray of such light enters a clear liquid pool at an angle of incidence of 30.0°, what is the angle of refraction?

Answer 1

We first need to find the index of refraction of the liquid given by n=5.22/2.85 = 1.83

We then use Snell's Law (1)sin(30)=1.84 sin θ

Therefore the angle of refraction = 15.8 degrees
