A light wave travels from medium 1 with a velocity of 2 x 108 m/s to medium 2 with a velocity of 1.5 x 108 m/s. If the angle of incidence is 30 degrees, what is the angle of refraction?
5 degrees
10 degrees
22 degrees
60 degrees
Using the formula
,
we can find
.
Substituting values,
Taking the inverse sine,
we get the angle of refraction as approximately 22 degrees.
