Question

what is sound ? and some sounds​

Answer 1

Explanation:

In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid. In human physiology and psychology, sound is the reception of such waves and their perception by the brain.

Answer 2

$\huge\tt{SOUND:}$

→ Sound is produced by vibrations. When an object vibrates, waves are generated by these vibrations in the surrounding air. These waves are only sound.

$\huge\tt{EXAMPLE:}$

→ Ring the school bell we will hear the sound of a bell.

→ while touching the ringing bell with our hand. we will feel the vibration in the bell.

→ If we hold the bell by hand, then the vibration in the bell stops quickly and the bell stops ringing, but if we do not hold the bell, the bell keeps vibrating for a long time and keeps ringing for a long time.

→ This proved that the sound of a bell is caused by its vibrations.
