Directions for: The questions consist of two statements each, printed as assertion and reason. While answering these questions you are required to choose any one of the following five responses A. If both the Assertion and the Reason are true and the Reason is a correct explanation of the Assertion. B. If both the Assertion and the Reason are true but the Reason is not a correct explanation of Assertion. C. If the Assertion is true but the Reason is false. D. If both the Assertion and the Reason are false. E. If Assertion is false but Reason is true.
Assertion: A turning fork is m resonance with a closed pipe. But the same tuning fork cannot be in resonance with an open pipe of the same length. Reason: The same tuning fork will not be in resonance with open pipe of same length due to end correction of pipe.A) A
B) B
C) C
D) D
E) E
Correct Answer: C
Solution :
If a closed pipe of length I is in resonance with a tuning fork of frequency v, then \[v=\frac{v}{4L}\] An open pipe of same length L produces vibration of frequency \[\frac{v}{2L}\]. Obviously, it cannot be in resonance with the given tuning fork of frequency \[v\left( =\frac{v}{4L} \right).\]
