An organ pipe `P_(1)` closed at one end vibrating in its first harmonic and another pipe `P_(2)` open at both ends vibrating in its third harmonic are in resonance with a given tuning fork. The ratio of the length of `P_(1)` and `p_(2)` is
(a) `8//3` (b) `3//8` (c ) `1//6` (d) `1//3`

A

`8//3`

B

`3//8`

C

`1//2`

D

`1//3`

Text Solution

Verified by Experts

The correct Answer is:
B
For first harmonic ,` n_(c) = 3v//4l_(1)` for third harmonic `n_(0) = 4v//2l_(2)`. Solving `l_(1)//l_(2) = 3//8
