At what angle from the vertical does the diver's friend see the Sun ? Assume the refractive index of water is 1.33.

Give your answer in degrees.

**julia**, Sunday, April 29, 2012 at 1:53pmIf the scuba diver is looking from the water n=1.33 and the other man is above water so n=1, use the equation n1sin(theta)=n2sin(theta).

1.33sin(20)=1sin(theta)

27.06 degrees is the answer, but since it says from the horizontal do 90-27.06
