Question

What is the purpose of this automated cleaning equipment?

1) To transmit sound waves through a cleaning solution
2) To clean surfaces using ultraviolet light
3) To remove stains using high-pressure water jets
4) To sanitize objects using steam

Answer 1

The purpose of the automated cleaning equipment is to transmit ultrasonic waves through a cleaning solution to remove contaminants through cavitation.

Step-by-step explanation:

The purpose of the automated cleaning equipment mentioned in the question is to transmit sound waves through a cleaning solution. Ultrasonic cleaners, which operate at frequencies typically around 40 kHz, are designed to clean items like jewelry, optical parts, and dental instruments. The cleaning is primarily achieved through a process called cavitation, where the ultrasonic waves create microscopic bubbles in the fluid. The energy released from these bubbles collapsing produces shock pressures that can penetrate small crevices and remove contaminants effectively.
