Pretend that a person can walk only at a certain pace—no faster, no slower. If you time her uninterrupted walk across a room of known length, you can calculate her walking speed. If. however, she stops momentarily along the way to greet others in the room, the extra time spent in her brief interactions gives an average speed across the room that is less than her walking speed. How is this similar to light passing through glass? In what way does it differ?

When high-energy charged particles move through a transparent medium with a speed greater than the speed of light in that medium, a shock wave, or bow wave, of light is produced. This phenomenon is called the Cerenkov effect. When a nuclear reactor is shielded by a large pool of water, Cerenkov radiation can be seen as a blue glow in the vicinity of the reactor core due to high-speed electrons moving through the water as shown. In a particular case, the Cerenkov radiation produces a wave front with an apex half-angle of 53.0°. Calculate the speed of the electrons in the water. The speed of light in water is 2.25 × 108 m/s.

Snell's Law Suppose that a light source at A is in a medium in which light travels at speed vị and the point B is in a medium in which light travels at speed v2 (see figure). Using Fermat's Principle, which states that light travels along the path that requires the minimum travel time (Exercise 65), show that the path taken between points A and B satisfies (sin 01)/v1 (sin 02)/v2.
