“…As a result, the solution undergoes strain and density. When the ultrasonic wave energy given is large enough, the wave strain can break the molecular bonds between solutions (16)(17)(18), and the gases dissolved in the solution will be trapped due to the solution molecules whose bonds are broken when a density returns. This results in hollow balls or bubbles filled with trapped gas, known as the cavitation effect.…”
