A glass of water (n = 1.33) has a layer of oil (n = 1.49) floating on top. (a) Calculate the critical angle for the oil-water interface. (2 marks) (b) If a ray of light traveling up through the water to the oil at an incident angle of 65.0°, will total internal reflection happen? (1 mark) (c) If a ray of light traveling down through the oil to the water at an incident angle of 65.0°, will total internal reflection happen? (1 mark)
