The fundamental frequency of a closed organ pipe is f. If both the ends are opened then its fundamental frequency will be?
Answer: 2f
Explanation
In a closed organ pipe, the fundamental frequency is f = v / 4L.
If both ends are opened, it behaves like an open pipe, and the fundamental frequency becomes f' = v / 2L.
So, f' = 2f.
