Question

An ultrasonic cleaner cleans dirty instruments using sound waves, which causes

A) Abrasion
B) Cavitation
C) Oxidation
D) Coagulation

Answer 1

The correct answer is B) Cavitation. Ultrasonic cleaners use sound waves to clean dirty instruments by causing cavitation. Cavitation is the formation and subsequent collapse of tiny bubbles in the cleaning fluid.

Step-by-step explanation:

The correct answer is B) Cavitation.

Ultrasonic cleaners use sound waves to clean dirty instruments by causing cavitation. Cavitation is the formation and subsequent collapse of tiny bubbles in the cleaning fluid. The collapse of these bubbles creates shock waves that help to dislodge dirt and contaminants from the surfaces of the objects being cleaned.

For example, in an ultrasonic cleaner, when the sound waves are sent into the fluid, they create millions of microscopic bubbles. As these bubbles collapse, they release energy in the form of shock waves that dislodge dirt and debris from the objects being cleaned, leading to effective cleaning.
