An organ pipe of length L is open at one end and closed at other end. The wavelengths of the three lowest resonating frequencies that can be produced by this pipe are

Options:

Answer:

Solution:

$L = (2 n - 1) \frac{λ}{4}$

$λ = \frac{4 L}{(2 n - 1)}$

$λ_{1} = \frac{4 L}{2 (1) - 1} = 4 L$

$λ_{2} = \frac{4 L}{4 - 1} = \frac{4 L}{3}$

$λ_{3} = \frac{4 L}{6 - 1} = \frac{4 L}{5}$
