Wave Mechanics Question 1115
Question: The fundamental note produced by a closed organ pipe is of frequency $ f. $ The fundamental note produced by an open organ pipe of same length will be of frequency
[BHU 2001]
Options:
A) $ \frac{f}{2} $
B) $ f $
C) $ 2f $
D) $ 4f $
Show Answer
Answer:
Correct Answer: C
Solution:
$ {n _{\text{closed}}}=\frac{v}{4l},{n _{\text{open}}}=\frac{v}{2l} $
Therefore $ {n _{\text{open}}}=2{n _{\text{closed}}}=2f $
