A) 50 Hz
B) 100 Hz
C) 150 Hz
D) None of these
Correct Answer: B
Solution :
When air is blown lightly at the open end of the closed pipe, then the air column vibrates as shown: The frequencies of fundamental tones and overtones of the closed pipe have the following relation \[{{n}_{1}}:{{n}_{2}}:{{n}_{3}}:......=1:3:5:.......\] that is, a closed pipe produces only odd harmonics. Hence, frequency of 100 Hz will not be emitted.You need to login to perform this action.
