Answer 1

Hi,

Ultrasonic vibrations are vibrations that have frequency in excess of 20,000 Hz and are therefore inaudible to human ears.

Two uses of ultrasonic vibrations:

1. Ultrasonics are used in medical diagnosis, particularly in condition such as pregnancy, in which X rays could have harmful effect.

2. Ultrasonic techniques are also used industrially to test for flaws in metal, to clean surface, to test the thickness of parts, and to form colloids.
