Decide the critical angle for the oil-water interface

Reference no: EM13660151

A glass is half-full of water, with a layer of oil (n =1.46) floating on top. A ray of light traveling downward during the oil is incident on the water at an angle of 70.8°. Take the refraction index of water to be 1.333. (a) Decide the critical angle for the oil-water interface.(b) Will the ray penetrate into the water?
