No, a radio wave is not a mechanical wave. A radio wave is a form of electromagnetic (EM) energy, and it does not require a medium through which to travel like a mechanical wave does. Radio waves can travel through the vacuum of space. Let's contrast that with a mechanical wave.

A mechanical wave involves the transfer of mechanical energy into and through a medium. Sound waves (which travel through air) and water waves (which move through water) are mechanical waves. They cannot travel without a medium through which to move.

Radio waves are electromagnetic radiation.

We have invented clever ways of changing the amplitude and frequency of radio waves according to patterns
that everyone has agreed on. Since the patterns of changes can be caused in one place and recognized in a
different place, they can be used to send 'coded' information from place to place, 'riding' on the radio waves.
In this way, radio waves are used as carriers for all kinds of information, such as sound, computer data,
TV pictures, etc.

If you can hear it, it's a sound wave.

The ear buds or speaker attached to the radio producessound waves. Before the signal

reaches the ear buds or the speaker, it's not a sound. There isn't really any such thing as

a "radio sound".

No. A FM radio is a collection of integrated and/or discrete components in an electrical

configuration capable of receiving and demodulating a frequency-modulated carrier.

There are radiowaves because it travels from the earth, but sounds from a radio is just sound made to go into your Ears
