Question:
E Investigate how a thin film of water on a glass surface affects the critical angle for total reflection. Take n = 1.5 for glass and n = 1.33 for water.
(a) What is the critical angle for total internal reflection at the glass–water interface?
(b) Is there any range of incident angles that are greater than θc for glass-to-air refraction, and for which light rays will leave the glass and the water and pass into the air?

The law of reflection states that the angle of reflection equals the angle of incidence ???????? = ???????? A bouncing ball obeys the “law of reflection,” which says that the ball leaves the surface at the same angle it approached the surface. The ball’s next bounce is 3.0 m to the right of its first bounce.
