A pipe open at both ends has a fundamental frequency $f$ in air. The pipe is now dipped vertically in a water drum to half of its length. The fundamental frequency of the air column is now equal to :NEET 2025

Options:

Answer:

Solution:

For open pipe $f = \frac{V}{2 ℓ}$ When half of its length is dipped in water, Now it is COP. $f^{'} = \frac{V}{4 ( ℓ /2 )} f^{'} = \frac{V}{2 ℓ} f^{'} = f$
