For a certain organ pipe, the first three resonance frequencies are in the ratio of 1 : 3 : 5 respectively. If the frequency of fifth harmonic is 405 Hz and the speed of sound in air is 324 m s -1 the length of the organ pipe is_____m.
Text Solution
Verified by ExpertsThe correct answer is:
1
(1)
It is given,
f s = 405 Hz.
As the first three resonance frequencies are in the ratio of 1 : 3 : 5, therefore it must be a closed organ pipe.
