Problem 32
Q

An aquarium filled with water has flat glass sides whose index of refraction is 1.54. A beam of light from outside the aquarium strikes the glass at a 43.543.5 ^\circ angle to the perpendicular (Fig. 23–56). What is the angle of this light ray when it enters

  1. the glass, and then
  2. the water?
  3. What would be the refracted angle if the ray entered the water directly?
