Topic hierarchy

16.1: Introduction
Sound is a longitudinal wave of pressure that travels through compressible medias, which can be solid, liquid, gaseous, or made of plasma.
16.2: Sound Intensity and Level
Sound Intensity is the power per unit area carried by a wave. Power is the rate that energy is transferred by a wave.
16.3: Doppler Effect and Sonic Booms
The Doppler effect is the apparent change in frequency of a wave when the observer and the source of the wave move relative to each other.
16.4: Interactions with Sound Waves
Superposition occurs when two waves occupy the same point (the wave at this point is found by adding the two amplitudes of the waves).
16.5: Further Topics
Spherical waves come from point source in a spherical pattern; plane waves are infinite parallel planes normal to the phase velocity vector.
