b) Find the apparent depth of the diver's head below water as seen by the instructor. Note, the bending of the light only changes the apparent vertical position of the diver, not its horizontal position. The picture is a bit confusing in this regard, the image of the diver is directly above its actual position: the horizontal distance is unchanged. 1.5 m

a) Given that the angle between the ray in the water and the perpendicular to the water is 29.7°, and using information in the figure above, find the height of the instructor's head above the water. Water has an index
of refraction equal to 1.333. This is a geometry problem.
