The fundamental frequency of an air column in a pipe closed at one end is $100 Hz$ . If the same pipe is open at both the ends, the frequencies produced in $Hz$ are

Options:

Answer:

Solution:

For a closed pipe fundamental frequency $n_{1} = \frac{V}{4 L} = 100 Hz$
For an open pipe fundamental frequency ${n'}_{1} = \frac{V}{2 L} = 2 n_{1} = 200 Hz$
In an open pipe all multiples of the fundamental are produced.
