Unformatted text preview: Waves and Sound AP Physics B What is a wave A WAVE is a vibration or disturbance in space. A MEDIUM is the substance that all SOUND WAVES travel through and need to have in order to move. Two types of Waves The first type of wave is called Longitudinal . Longitudinal Wave - A fixed point will move parallel with the wave motion 2 areas Compression- an area of high molecular density and pressure Rarefaction - an area of low molecular density and pressure Two types of Waves Transverse Wave - A fixed point will move perpendicular with the wave motion. The second type of wave is called Transverse . Wave parts(recall demo for simple harmonic motion )- crest, trough, wavelength, amplitude, frequency, period Wave Speed You can find the speed of a wave by multiplying the wave’s wavelength in meters by the frequency (cycles per second). Since a “cycle” is not a standard unit this gives you meters/second. Example A harmonic wave is traveling along a rope. It is observed that the oscillator that generates the wave completes 40.0 vibrations in 30.0 s. Also, a given maximum travels 425 cm along a rope in 10.0 s . What is the wavelength?10....
