description of how sound travels

Hello

Is there anything inaccurate or plain wrong about the following statement

Vibrating objects create sound. As the vibrating object moves back and forth it bangs into neighbouring air molecules. The air molecules start to move in the same pattern as the vibrating object (back and forth). They then knock into their neighbours. In this way the sound is passed across air as a wave of vibrations.

My main concern is whether it is ok to say it is a wave of vibrations. I think this is intuitive as kids can imagine a vibrating object and then a ripple effect in the air

thanks

Yes. Wave of vibrations is exactly what is happening. The ripple effect you see in water is actually very similar to the way sound waves propagate. I think that is a very good example.

yes..sound is produced by vibrations. I would just add one more line to your sentence : vibration needs a medium to travel through.

Sound waves exist as variations of pressure in a medium such as air. They are created by the vibration of an object, which causes the air surrounding it to vibrate. The vibrating air then causes the human eardrum to vibrate, which the brain interprets as sound.

Frequency is the number of those vibrations of sound travelling through air, water or another medium.The measure of the frequency of sound is Hertz (Hz) per second. Humans can hear frequencies of sound in the range of 20Hz per second to 20,000 Hz per second. Many vibrations of sound are above and below our range of hearing, seeming to be silent.

Yes. you can tell that sound is caused by vibration traveling in a medium (medium is required. in vacuum there is no sound. Because, there is no air)
