Question by VictoriousV: A pencil going through the surface of the water appears to bend slightly?
A pencil going through the surface of the water appears to bend slightly where it crosses the surface. The pencil enters the water with an angle of 45 degrees to the vertical. If an observer is looking at the pencil approximately from above, at what angle does the pencil appear to bend (by how many degrees does its image diverge from a straight line)? Assume that the index of refraction of water is 1.33.
