1.Wavelength – 1.In transverse waves – distance between two crests or troughs 2.In longitudinal waves – distance between two compressions or rarefactions 2.Frequency – the number of waves that pass a point in one second 1.Long wavelengths have low frequencies 2.Short wavelengths have high frequencies 3.Amplitude (wave height) – the distance from the middle of a transverse wave to the crest or trough
