Unformatted text preview: Chapter 8: Boundary Effects and Interference (pp. 274280, up to Double-Slit Interference). Chapter 8: Boundary Effects and Interference Doppler Effect and Related Phenomena (p. 274) The discussion here relates to waves for which Galilean relativity applies. Light waves (from a source of light) spread out in circles at the velocity of light c (310 8 m/s), independent of the speed at which the source is moving. This is one of the fundamental postulates of special relativity. Relativity means that there is no way to define which is at rest, the source or the observer, while in the cases cited here, the medium itself is at rest, defining a frame of reference. The video lecture discusses the Doppler effect for electromagnetic radiation....
