A spotlight on a boat is y = 2.6 m above the water, and the light strikes the water at a point that is x = 8.6 m horizontally displaced from the spotlight. The depth of the water is 4.0 m. Determine the distance d, which locates the point where the light strikes the bottom.
Find the angle of incidence (arctan8.6/2.6)
then use snells law to find the angle of refraction.
I am not certain if d is the distance from the boat...assuming so...
