Question

distinguish between in infrasonic waves and ultrasonics

Answer 1

Ultrasonic waves are acoustic waves that are so high in frequency that humans can't hear them; however, infrasonic waves are sound waves that are lower in frequency than what humans can hear. A subsonic wave is a wave that is traveling slower than the speed of sound and a supersonic waves travels faster.

Answer 2

Sound frequencies that cannot be heard by human ears are called infrasonic waves. These waves have lower frequencies than 20Hz.

Sound frequencies above 20,000Hz (20 kilohertz) are called ultra sonic waves. These waves also cannot be heard by human ears.
