Define the following terms: Period Frequency Wavelength Amplitude Compression Rarefaction

Period: The period of a wave is the time it takes for one complete cycle of the wave to pass a given point. It is usually measured in seconds.<br /><br />Frequency: The frequency of a wave is the number of complete cycles that pass a given point per unit of time. It is usually measured in hertz (Hz), which is equivalent to one cycle per second.<br /><br />Wavelength: The wavelength of a wave is the distance between two consecutive points in the wave that are in phase. It is usually measured in meters.<br /><br />Amplitude: The amplitude of a wave is the maximum displacement of a point on the wave from its rest position. It is usually measured in meters or other units of length.<br /><br />Compression: In a longitudinal wave, a compression is a region where the particles are closest together. This is the region of maximum density and pressure in the wave.<br /><br />Rarefaction: In a longitudinal wave, a rarefaction is a region where the particles are furthest apart. This is the region of minimum density and pressure in the wave.
