Introduction A supersonic wave means a wave higher than audio frequency and generally stands for a frequency more than 16 KHz. Once the supersonic wave is launched in solvent, expansion and contraction occur in the liquid by the vibration of molecules and, when the energy of the supersonic wave becomes larger, the cohesive power of the liquid
