Question

Name the part which vibrates to produce sound in the following:

(1) Drums

(2) Sitar

(3) Flute

Answer 1

Sound:

1. Sound is considered a form of energy/pressure wave created by a vibrating substance.
2. When a body vibrates, it creates a pressure wave, which produces sound.
3. This pressure wave generates vibrational motion in the molecules in the nearby medium.

In the following instruments, the sound is produced by:

(1) Drums: Sound in drums is produced because of the stretched membrane.

(2) Sitar: The sitar produces sound because of its strings, which vibrate when stretched.

(3) Flute: Sound in the flute is produced because of the long hollow pipe.
