Question

Which of these statements accurately describe uses of ultrasound technology? Check all that apply.

It is unsafe to use for industrial applications.
It can be used to clean small items like jewelry.
It can be used to clean large items like machinery.
It increases the production time of everyday materials.
It cannot be used in the presence of liquids like water.

Answer 1

Correct:
- It can be used to clean small items like jewelry.
- It can be used to clean large items like machinery (with industrial/portable ultrasonic systems or specialized tanks).

Incorrect:
- It is unsafe to use for industrial applications — false; ultrasound is widely used safely in industry (cleaning, inspection, welding, etc.) when proper controls are used.
- It increases the production time of everyday materials — false; ultrasonic processes often speed or improve manufacturing (e.g., welding, degassing, cleaning).
- It cannot be used in the presence of liquids like water — false; many ultrasonic applications (especially cleaning) rely on liquids and cavitation.
