Assertion : Two successive frequency of ...

Assertion : Two successive frequency of an organ pipe are `450 H_(Z)` and `750 H_(Z)` . Then, this pipe is a closed pipe.
Reason : Fundamental frequency of this pipe is `150 h_(Z)`.

A

If both Asseration and Reason are true an dthe Reason is correct explanation of the Asseration.

B

If both Asseration and Reason are true but Reason is not the correct explanation of Asseration.

C

If Asseration is true , but the Reason is false.

D

If Asseration is false but the Reason is true.

Text Solution

Verified by Experts

The correct Answer is:
B
`(450) / (750) = (3) /(5)`
Successiver harmonics are odd `3` and `5`. Hence, it is a closed pipe.
