Question

how does pitch of a sound produced by a flute depend on lenght of the air column​

Answer 1

Answer:

The shorter the column of air, the faster the air vibrates. The faster the vibrations, the higher the pitch. The sound produced depends on the amount of air in the tube. ... As the column of air shortens, the pitch rises.

Explanation:

This double reed fits into a tube at the top of the instrument and vibrates when air is forced between the two reeds. Woodwind pitch depends on the volume of air that is vibrating. A larger volume vibrates more slowly, for lower pitch; a smaller volume vibrates more quickly, for a higher pitch.
