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 0₂ = 35°, measured from the normal to the interface.

Transcribed Image Text: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 0 = 35°, measured from the normal to the interface.
Known Variables
0₂=35°
945
Find the height of the instructor's head above the water in meters, noting that you will first have to
= 1.33
calculate the angle of incidence (you can take the indices of refraction to be n = 1 for air and n
for water).
h =
Find the apparent depth of the diver's head below water as seen by the instructor in meters, assuming the
diver and his image both have the same horizontal distance along the surface of the water.
