ultrasonic means their frequency is too high for us to hear, infrasonic means their frequency is too low for us to hear. This is analogous to the electromagnetic spectrum, where ultraviolet light has too high a frequency for us to see, and infra-red light has too low a frequency for us to see.

Compare ultrasonic and infrasonic?

The definition of infrasonic is relating to sound waves with a frequency below the limit of human hearing, 20 Hz. Ultrasonic relates to sound waves with a frequency above the limit of human hearing, 20,000 Hz.

What are ultrasonic and infrasonic sound waves?

Ultrasonic and Infrasonic sound waves are waves that are not audible to human beings. The audible region contains sound waves of 16 Hz to 20,000 Hz.Infrasonic sound waves have frequencies below 16 Hz. For example, an earthquake.Ultrasonic sound waves have frequencies above 20,000 Hz. For example, x-rays.Grade 11 Physics

Distinguish between infrasonic and ultrasonic sound?

Infrasonic denotes any sound that is at a frequency below the human capability of hearing, this is around 5-25Hz. Ultrasonic on the other hand is, conversely, a frequency that is above the human hearing range (over 20,000Hz).


Why ultrasonic waves are not electromagnetic waves?

No. They are mechanical waves, ultrasonic waves are sound waves and require a medium for propagation. The word ultrasonic denotes that they have a frequency above the audible range (above 20 KHz).

Are ultrasonic waves called as electromagnetic wave?

No ultrasonic waves are not a form of electromagnetic wave. Ultrasonic waves are nothing more than high frequency sound waves. They can be made with a suitable speaker or transducer.


Can ultrasonic wave pass through 1Cm thick iron plate?

Yes. Ultrasonic waves can pass through metal. The only difference between "normal" sound waves and ultrasonic waves is that we cannot hear ultrasonic waves. However, they behave the same.
