Question

What is sound and how it is produced?

Answer 1

Hint: Basically sound waves are created by vibrating the body. The sound source creates vibrations in the surrounding medium. As the source continues to vibrate the medium, the vibration propagates away from the source at the speed of sound, thus forming the sound wave.

Complete step by step answer:
A form of wire which is produced by a vibrating body travels through the air medium makes the propagation of vibration. These Vibrating waves travel in the medium until it reaches our ear and that signal is being sent to the brain.
The vibrating wires are called sound.
Production of sound is solely dependent on the waves and how it collides with other particles that are adjacent to each other in the medium. In this medium there is compression and rarefaction of the air particle. This whole phenomenon creates a disturbance and thus we can hear it is a sound.
There are some basic properties of sound:
1. Propagation of sound waves is due to compression and rarefaction of the air particle.
2. Frequency of sound waves is known as the number of oscillations per unit time. The SI unit of the sound wave is Hertz (Hz).
3. Wavelength is the length of one oscillation. SI unit of wavelength is meter (m).
4. Time period is the time at which a wave moves the distance equal to its wavelength.

Note:
Sound is defined as vibrations that travel through air or another medium as an audible mechanical wave. It is produced from a vibrating body. The vibrating body causes the medium (water, air etc.) around it to vibrate these producing sounds.
