GENERAL KNOWLEDGE

Detailed explanation-1: -Explain that the fast back-and-forth motion of the rubber band is called a vibration. When you pluck the rubber band, you make it vibrate.

Detailed explanation-2: -Thicker, heavier, and loosely stretched rubber bands will sound lower pitched, while thinner, lighter, tightly stretched rubber bands will sound higher.

Detailed explanation-3: -When a stretched or taut rubber band is plucked, the band undergo fast vibrations. These vibrations are responsible for production of sound.

Detailed explanation-4: -Vibration is the backward and forward movement of a body. Sound is caused by vibration that makes particles in the air form sound waves. A damper is used to reduce vibration. Vibration is the backward and forward movement of a body.

Detailed explanation-5: -Sound waves are produced by a vibrating body. The vibrating object moves in one direction and compresses the air directly in front of it. As the vibrating object moves in the opposite direction, the pressure on the air is lessened so that an expansion, or rarefaction, of air molecules occurs.
