Question

in wind instruments pitch of sound increases when length of air column is ________​

Answer 1

A change in wavelength will result in a change in the frequency. So the natural frequency of a wind instrument such as the trombone is dependent upon the length of the air column of the instrument. Therefore, as the length of a vibrating column increases, its frequency decreases and vice versa

Answer 2

Answer: A change in wavelength will result in a change in the frequency. So the natural frequency of a wind instrument such as the trombone is dependent upon the length of the air column of the instrument.
