Question

Sound is produced by vibrations. prove that.

Answer 1

Answer.
Sound is produced when somethingvibrates. The vibrating body causes the medium (water, air, etc.) around it to vibrate. Vibrations in air are called traveling longitudinal waves, which we can hear. Sound waves consist of areas of high and low pressure called compressions and rarefactions, respectively.

I hope u understand and plz mark brainliest

Answer 2

the concept of sound produced by the vibration of an object with an example. We might have seen people playing guitar. In guitar when they pluck the strings of a guitar, it vibrates and produces sound. The sound produced by it travels through the air which acts as the medium.A good way might to find a sound-producing object, and film it at high speed, if you have the equipment. You will see when you look at the film that the object, e.g. a tuning fork, is in fact moving back and forth. If you are ambitious, you can measure the volume of sound, and compare with the amplitude of the oscillation observed on the film. You should see a nice, linear relationship between the amplitude and the sound volume. You can also do this with frequency.

Tuning forks are particularly useful for this kind of experiment, because their sound, and vibration last a long time before dying out.

This experiment will prove that some sound-producing things vibrate, at an amplitude that seems connected to the sound volume. It does not prove that all sound is produced by vibration, or even that vibration causes sound, rather than being a byproduct of it. But it suggests it strongly.
