tangent of the angle of incidence. The diameter of the circle in question is given by d = 2 h tan θ c . For water n = 1.33, so Eq. 33-47 gives sin c = 1/1.33, or c = 48.75°. Thus, 2 tan 2(2.00 m)(tan 48.75 ) 4.56 m. c dh == ° = (b) The diameter d of the circle will increase if the fish descends (increasing h ). 60.
