​sound

Sound is a form of energy produce by vibrations.

Sound plays an important part in our daily lives. It helps us to communicate with each other. We hear a wide variety of sounds in our surroundings.

Sound is produced by a vibrating body.

Vibration is the to and fro or back and forth motion of an object.

Eg :- If you strike a school bell, it vibrates and produces sound. If you pluck a stretched rubber band, it vibrates and produces sound. If you beat a drum, its stretched membrane vibrates and produces sound. If you blow a bugle, the air column vibrates and produces sound.
