How to do Q3b-d?

3. A fish is 3 m below the surface of a lake. The D objects above the surface of the lake appear to have been compressed inside a cone. The refractive index of the lake water is 1.35 air water (a) What is the angle of incidence of the light travelling along the air-water boundary? (b) What is the angle of refraction when light first enters into the water? (c) What is the angle of the fish-eye view? (d) What is the diameter of the base of the cone (D) on the water surface?
