Where φ1 is the angle of incidence, φ2 is the angle of refraction, η1 is the refractive index of medium 1 (water), and η2 is the refractive index of medium 2 (air).
The angle underwater is φ1 = 90° - 59° = 31°
(1.33)sin(31°) = (1)sin(φ2)
An underwater diver sees the sun 59 degrees above horizontal.
What is the angle between the sun and the fisherman relative to the horizon?
Express your answer using two significant figures.
