I cant figure this problem out? Can someone please help. Thanks.
A glass is half-full of water, with a layer of vegetable oil (n = 1.47) floating on top. A ray of light traveling downward through the oil is incident on the water at an angle of 65.2°. Determine the critical angle for the oil-water interface and decide whether the ray will penetrate into the water.
thanks so much for the answer!!!! you're a life saver
