Aglass is half-full of water, with a layer of oil (n = 1.46) floating on top. a ray of light traveling downward through the oil is incident on the water at an angle of 73.7°. take the refraction index of water to be 1.333. (a) determine the critical angle for the oil-water interface. (b) will the ray penetrate into the water?
