We introduce waves by considering solutions to the wave equations for propagation along a string.  We introduce the concepts of superposition and standing waves.

Review of Chapters 1-8

Review of chapters 13-16

We look at wave effects for sound including interference and beat notes and the doppler shift caused by a moving listener or source.

Doppler Shift and Interference

We continue to look at mechanical waves, focusing on sound and hearing, specifically the decibel units for sound level.
