Imagine a ray of light passing between air (n~1) and glass (n~1.5). If the ray of light hits the glass from the air at an angle of 60 degrees, what will the new angle of the light be relative to that air-glass interface as it travels through the glass? (Hint: Remember that you need to focus on the angle of the light relative to a line perpendicular to the air-glass interface when using Snell's Law)

1. Consider a cuboid made of crown glass which has inner space filled with water. A ray of light is incident onto the 10 cm thick block of glass on the top face of the cuboid at 60◦ from the normal. It then meets the glass-water boundary and is refracted again and continues through a water thickness of 5 cm before reaching another water-glass boundary. The ray of light is again refracted and continues in the 10 cm thick block of glass on the base of the cuboid and eventually exits into air. (a) Draw a clearly labelled diagram of the path the ray of light takes. (b) Calculate all the angles of refraction and incidence at each boundary. (c) Calculate the optical path of the ray of light from the point it is incident on the surface of the cuboid to the point it exits into air on the other end.
