Explanation:
Detailed explanation-1: -Sound is derived from objects that vibrate producing pressure variations in a sound-transmitting medium, such as air. A pressure wave is propagated outward from the vibrating source.
Detailed explanation-2: -When an object vibrates, it causes movement in surrounding air molecules. These molecules bump into the molecules close to them, causing them to vibrate as well. This makes them bump into more nearby air molecules. This “chain reaction” movement, called sound waves, keeps going until the molecules run out of energy.
Detailed explanation-3: -Vibration is the backward and forward movement of a body. Sound is caused by vibration that makes particles in the air form sound waves.
