The figure on the left below shows a small lightbulb suspended
at distance d1 = 250 cm above the surface of
the water in a swimming pool where the water depth is
d2 = 200 cm. The bottom of the pool is a large
mirror. How far below the mirror's surface is the image of the
bulb? (Hint: Construct a diagram of two rays like that of the
figure on the right, but take into account the bending of light
rays by refraction. Assume that the rays are close to a vertical
axis through the bulb, and use the small-angle approximation in
which sin(?) 
tan(?)
?.)

(8%) Problem 3: Consider the situation in the figure -a student diver in a pool and an instructor on the edge, outside the water. Since the indices of refraction of air and water are different, the light rays coming from the diver and the instructor are refracted at the surface, changing their apparent position with respect to each other. The diver sees the instructor at an apparent angle of e, - 33", measured from the normal to the interface Randomized...
