Solution

Q.
In an experiment with a closed organ pipe, it is filled with water by $(\frac{1}{5}) th$ of its volume. The frequency of the fundamental note will change by [2025]

1 25%

2 20%

3 –20%

4 –25%

Ans.
(1)

$f_{1} = \frac{v}{2 l}, f_{2} = \frac{v}{2 (\frac{4 l}{5})} = \frac{5}{4} f_{1} = 1.25 f_{1}$

$100 \times \frac{△ f}{f} = 25 %$
