Waves Webquest

Longitudinal and transverse waves are demonstrated. Longitudinal waves involve compression and rarefaction while transverse waves involve displacement perpendicular to the direction of travel. Examples are given of each type of wave. The parts of a wave like crest, trough, amplitude and wavelength are defined. Frequency is measured in Hertz and is inversely related to wavelength - higher frequency means shorter wavelength. Changing properties like frequency, amplitude and tension impact wave patterns in predictable ways.
