Ultrasound is a technique used to clean hard-to-reach places. Which of the following statements best describes how ultrasound achieves this?
 

Ultrasound cleaning deploys high-frequency sound waves to eliminate dirt and contaminants from inaccessible areas through cavitation. As ultrasound waves traverse a liquid, they create alternating pressure cycles, forming and imploding tiny bubbles. This bubble implosion generates shock waves, high-velocity microjets, and localized extreme temperature and pressure areas near the cleaning surface, effectively dislodging dirt.
