Question

6) An underwater diver observes that the angle of the Sun, relative to the perpendicular, appears to be θ relative to the vertical. Assign a value for θ = 28°

a) Sketch and label a ray diagram illustrating the scenario (3 points).

b) If water has an index of refraction of 1.3 and air has an index of refraction of 1.0, what is the true angle of the Sun relative to the vertical (4 points)?

c) An underwater driver observes a light ray that travels from the Sun. When the incident ray hits the air-water barrier, some of the light reflects off the surface of the water. What is the angle of reflection (2 points)?
