A scuba diver training in a pool looks at his instructor as shown in the figure. What angle does the ray from the instructor’s face make with the perpendicular to the water at the point where the ray enters the water? The angle between the ray in the water and the perpendicular to the water is 40.0°. Note: the index of refraction of air is 1.00; the index of refraction of glass is 1.50; the index refraction of water is 1.33.
