Explanation:
It is given that, the range of human hearing is roughly from twenty hertz to twenty kilohertz.
Minimum frequency, f = 20 Hz
Maximum frequency, f' = 20,000 Hz
We need to find the lengths of the longest and shortest pipes. For open pipes, the length of pipe is given by :
For shortest pipe, frequency should be maximum,
l = 0.008575 m
For longest pipe, frequency should be minimum,
l' = 8.575 m
So, the lengths of longest and shortest pipes are 8.575 meters and 0.008575 meters respectively.
