. Two narrow cylindrical pipes A and B have the same length


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 MA. Pipe B is open at one end and closed at the other end, and is filled with a diatomic gas of molar mass MB. Both gases are at the same temperature

A. If the frequency to the second harmonic of the fundamental mode in pipe A is equal of the frequency of the third harmonic of the fundamental mode in pipe B, determine the value of MA/MB.

B. Now the open end of the pipe B is 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.

 

Best Answer

Frequency of second harmonic in pipe A = frequency of third harmonic in pipe B

Frequency of second harmonic

(B) Ratio of fundamental frequency in pipe A and in pipe B is:

Frequency of second harmonic
