Question

Choose the correct option and explain:

How is the sound produced in a bamboo flute?

(A) By the vibrations of air molecules inside the bamboo
(B) By the vibrations of bamboo
(C) By hitting the bamboo
(D) By a change in the direction of air​

Answer 1

Answer:

(A) by the vibrations of air molecules inside the bamboo

Explanation:

A flute produces sound when a stream of air directed across a hole in the instrument creates a vibration of air at the hole. The airstream creates a Bernoulli or siphon. This excites the air contained in the usually cylindrical resonant cavity within the flute

Answer 2

(A) By the vibrations of air molecules inside the bamboo

Sound is always produced by the vibration of the particles of the medium. In flute's case, it's the vibrations of air molecules inside it.
