What is the mechanical process that allows ultrasonic cleaners to work?

Ultrasonic cleaners function through the principle of cavitation, which is the formation and implosion of tiny bubbles in a liquid. This process occurs when high-frequency sound waves, generated by transducers within the cleaner, pass through the cleaning solution, creating alternating high-pressure and low-pressure waves. As the pressure drops during the low-pressure cycle, microscopic bubbles form in the liquid. When these bubbles implode during the high-pressure cycle, they produce powerful shockwaves that dislodge dirt, debris, and contaminants from the surfaces of items being cleaned.

Cavitation is essential for the effective cleaning action of ultrasonic cleaners, allowing for thorough cleaning in hard-to-reach areas, making it particularly effective for intricate instruments or delicate objects. The efficacy of this process underscores the importance of cavitation in ultrasonic cleaning systems.

Other processes listed, like oscillation, vibration, and agitation, are related concepts but do not accurately describe the specific mechanism at work in ultrasonic cleaning. Oscillation refers to a repeated motion and while it occurs, it's not the defining principle. Similarly, vibration is a broader term that describes motion in response to sound, but again doesn't capture the unique cleaning mechanism of bubble implosion that characterizes cavitation. Agitation implies a more general stirring or
