physics

amplitude is measured by: line to the crest (height)

wave length is measured by: crest to crest or troft to troft

detructive wave colide and: the waves cancel out

constuctive waves colide and: both waves equal to a bigger wave

shorter wavelength = higher frequency

transverse waves: the virbration is perpendicular to the direction of the wave (water, electromagnetic)

longitudinal waves: the vibration is in the same direction as the wave is traveling (sound)

meduim: what the wave is traveling through
