A pipe closed at one end open at the other end,
resonates with sound waves of frequency 135 Hz and
also 165 Hz, but not with any wave of frequency
intermediate between these two. Then, the frequency
of the fundamental note is

A

30Hz

B

15Hz

C

60Hz

D

7.5Hz

Text Solution

Verified by Experts

The correct Answer is:
B
`n_1-n_2` = 165 - 135 = 30
The difference between two successive harmonics = 2 fundamental frequency
`30 therefore 2n therefore n = 15Hz`
