Angle at which under water diver sees the sun from horizontal =
Angle from normal direction = 90 - 57 =
Refractive index of water = 1.33
Refractive index of water = 1
We have the equation
1.33 * sin = 1 *sin
=
This angle is angle from normal, so angle seen by fisherman from horizontal = 90 - 46.42 =
