Due to the longitudinal pressure wave nature of ultrasound as it passes through various media, the characteristics of each contact are determined by the wavelength and velocity of the beam.The linked effects are not confined to the molecular level . Ultrasound, in contrast to other forms of energy like heat and light, can be used to enhance physicochemical reactions by producing extremely transient local temperatures, high pressures, and mechanical stresses . In theory, an effect known as ultrasoundinduced cavitation may mediate such a mechanism . In chemical reactions that take place in water, the cavitation effect is most prominent; this occurs when the aqueous phase is compressed and then expanded as a result of successive ultrasonic irradiation. Because the ultrasonic liquid's vapor pressure is lower than that of the compressed liquid, microbubbles made of gas and liquid vapour are created .
