Determine the critical angle for the oil-water interface

Reference no: EM13565099

A glass is half-full of water, with a layer of oil(n = 1.51) floating on top. A ray of light traveling downward through the oil is incident on the water at an angle of 72.9°. Take the refraction index of water to be1.333. (a) Determine the critical angle for the oil-water interface.
