Question

How sound is produced in flute or clarinet?
A) Air in the tube vibrates
B) Skin of flute vibrates
C) The holes of the flute vibrates
D) No vibration is produced.

Answer 1

Hint
The sound from flute comes due to the vibrating columns of air inside it. When air is blown into instruments it vibrates and then made to resonate to produce sound.

Complete step-by-step answer

In a flute, the air gets vibrated and the resonator amplifies the vibration and gets modified into sound. When the player blows air into the flute, the air rapidly vibrates by going into and away from the holes. This continues till the resonance of the tube where the sir stream begins fluctuating in and out of the tube making rapid successions and more vibrations. When the vibrations are set up, the air movement in the tube becomes a series of contractions and expansions. The push given by the breath fluctuates simultaneously with each contraction. This makes the vibration build to such a point where it can vibrate the air around it as well and hence the sound is produced.
Therefore, the correct option is A.

Note
Any musical sound produced by simple harmonic oscillations of the source is called note. Every musical sound consists of different frequencies; every component of a set of particular frequencies is known as tone. For instruments like the Tabla, the stretched membrane is loaded at the center; its overtones become nearly harmonic making the sound more musical.
