Asked by Zeno

A light ray in air strikes the surface of a lake at an angle of incidence of 46 degrees. What is the angle of refraction in the water?
Answered by drwls
Snell's Law says that
1.0* sin I = N*sin R

Use water's index of refraction N to calculate the angle R.

Look up the index of refraction. It is about 1.33
