Answered by admin @
Hello friend!
Here's ur answer!
Sound is a form of energy that produces the sensation of hearing in our ear.
Sound is produced when a body vibrates.
Experiment 1:
Stretch a string by holding one end in mouth between the teeth and the other end in one hand. Pluck it by the other hand near the middle.
It is noticed that the string starts vibrating and simultaneously a sound is heard. After some time when the dtring stops vibrating, no sound is heard.
Experiment 2:
Take a thin wife and stretch it between the two nails about a meter apart. Place a small but if paper as rider near the middle of the wire and pluck the wire near the rider.
It is observed that the rider flies off as the wire starts vibrating and a sound is heard. After sone time, when the wire stops vibrating, when the paper rider placed on the wire, doesnt fly of and no sound will be heard.
Experiment 3:
Take a tuninf fork which is a rectangular rod of steel bent in the U shaped, with a metallic stem at thevbend. Strike it's one arm in a rubber pad and bring it near a table ball suspended by a thread.
It is noticed that as the arm of vibrating timing fork is brought close to the ball, it jumos to and fro and sound of the vibrating tuning fork is heard. When the arm stops vibrating, the ball becomes stationery and no sound Is heard.
HOPE IT HELPS!! ☺
