[20 points] As shown in the figure, a searchlight mounted on a boat is at a height c = 2 [m] above the water surface. The light beam strikes the water (nwater = 1.3) at a horizontal distance b = 7.5 (m) from the spotlight. The depth of the water is a = 3 [m). ta b K 1 a 1 d 1 A. [5 points) At what angle of incidence the light ray strikes the water? 01 B. (2 points) Which formula can be used to calculate the angle of refraction 02? C. [3 points) If 0 = 789, calculate the angle of refraction 02. 02 =
D. [5 points] If 0, = 78° and O2 = 52°, what is the deviation angle Ap for this light incident from air into water? өр E. [5 points) If O2 = 52°, determine d, the horizontal distance between the searchlight and the point where the light strikes the bottom d = m
