Document Summary
No single air molecule moves far; the wave moves through the medium. Traveling zones of: compression = greater r rarefaction = lesser p. Period (t), frequency (f ), and wavelength ( ) are all related to each other. The speed of the wave is independent of t, f, and . The speed of sound is related to physical properties of the medium through which it is travelling. We are talking about sound in air, so we can stick to certain numbers. A wave will travel until through a medium until one of two things happen: Travels around its merry way until physics take over. A wave hits an object, and it is reflected back ! When a wave is reflected back, a standing wave can happen. Amplitude and frequency of a blue wave, amplitude and frequency of a red wave, as they cross eachother, the two amplitude aff to eachother. We have this phenomenon of a standing wave.
