(a) Given that the angle between the ray in the water and the perpendicular to the water is 25.0°, and using information in Figure 25.51, find the height of the instructor's head above the water, noting that you will first have to calculate the angle of refraction. 

(b) Find the apparent depth of the diver's head below water as seen by the instructor. Assume the diver and the diver's image are the same horizontal distance from the normal.
