In the fundamental mode, time taken by the wave to reach the closed end of the air filled pipe is $0.01 s$ . The fundamental frequency is

Options:

Answer:

Solution:

In the fundamental mode, Frequency, $n = \frac{v}{λ}$ $n = \frac{v}{4 l} n = \frac{l}{t \times 4 l} [∵ v = \frac{l}{t}] n = \frac{1}{0.01 \times 4} n = 25$
