Determine the length of a wind instrument, assuming that it is modeled as a closed tube and that the lowest sound that it can play has a frequency of 99 hz. the speed of sound in air is 343m/s.

Length, l = 0.866 meters

Explanation:

Given that,

Frequency of sound, f = 99 Hz

Speed of sound in air, v = 343 m/s

To find,

The length of a wind instrument.

Solution,

The standing wave will gets formed in wind instrument. For the closed tube, the closed tube the frequency is given by :

Where

l is the length of the instrument

l = 0.866 meters

So, the length of a wind instrument is 0.866 meters. Hence, this is the required solution.
