Ultrasonic cleaning is superior to manual scrubbing because of which of the following?
Correct Answer:the cavitation action can reach small areas in the instrument that brushes cannot When an ultrasonic wave passes through a liquid, it makes the liquid vibrate very fast. The vibrations are transmitted through the detergent bath and create cavitation. This is where ultrasonic vibrations create tiny air bubbles that grow larger until they implode. That implosion dislodges soil from the instrument's surface, as well as crevices, hinges, and other hard to reach areas within the instrument. Ultrasonic cleaning is superior to manual scrubbing because the cavitation action can reach small areas in the instrument that brushes cannot.
