 Crest the section of the wave that rises about the undisturbed position, it is the highest point in a transverse wave Trough the section of the wave that lies below the undisturbed position, it is the lowest point in atransverse wave Amplitude The maximum positive displacement from the undisturbed position of the medium to the top of a crest or the distance from the rest position straight up to the crest or trough. Wavelength the distance between any two adjacent correspoinding locations on the wave train. This distance is usually measured in one of three ways: crest to crest, trough to trough, or the distance from the rest position, straight up to the crest or down to the trough. Medium the matter that most waves travel through or material Median/Rest Position/Undisturbed Medium Where the particles of a medium stay when thereare no disturbances Frequency how many waves are made per time interval and is measured in Hertz or Hz Speed The speed at which the waves travel, the speed of a wave depends on the medium in which the wave is traveling Wave Equation Speed of the wave = Frequency x Wavelength or V=f*λ Parts of a wave Wave equation if no frequency V=s/t or Speed=distance/time Transverse Waves a wave that's direction of motion is 90o to the motion of its medium. Longitudinal wave particles of medium move back and forth along the same direction of wave, has 2 distinct regions - compression and rarefaction, sound waves.
