longitudinal and transverse waves

longitudinal waves Longitudinal waves have rarefactions which is when the particles are spread out. Compressions are when the particles have been squashed together When sound travels, it travels in a longitudinal wave

transverse waves the amplitude and wavelength on a transverse wave is perpendicular (meet at a right angle) all the time. when light travels, it travels in a transverse wave the crest is the highest point of a wave. the tough is the lowest point of a wave.
