Trough. Transverse wave is the form of wave in which particles of medium vibrates about their mean position perpendicular to the direction of the motion of the wave. It's practically what you dependence currently. This is the process of a wave bouncing off an object at the same angle it hit. The range of audible frequencies is from about 20 $\mathrm{Hz}$ to $20,000 \mathrm{Hz}$ . In human physiology and psychology, sound is the reception of such waves and their perception by the brain. In a surface wave, the particles vibrate both up and down and from side to side, so they end up going around in a circle. Crest.
