For one closed pipe and one open pipe, frequencies of their first harmonics are same. Find ratio of their lengths.

A

`1:2`

B

`2:3`

C

`3:4`

D

`4:5`

Text Solution

Verified by Experts

The correct Answer is:
A
For closed, pipe, frequency of first harmonic,
`f._(a) = (v)/(2L)`
`therefore (f _(1))/(f._(1)) = (v)/(4L) xx (2L)/(v) = 1/2`

Two narrow cylindrical pipes A and B have the same length. Pipe A is open at both ends and is filled with a monoatomic gas of molar mass M_(A) . Pipe B is open at one end and closed at the other end, and is filled with a diatomic gas of molar mass M_(B) . Both gases are at the same temperature. (a) If the frequency of the second harmonic of the fundamental mode in pipe A is equal to the frequency of the third harmonic of the fundamental mode in pipe B , determine the value of M_(B)//M_(B) . (b) Now the open end of pipe B is also closed (so that the pipe is closed at both ends). Find the ratio of the fundamental frequency in pipe A to that in pipe B .
