Question

Find the frequency of a 63.8-cm long open end air column

that resonates as shown in the diagram at the right. The speed of sound in the air is 345 m/s.

Answer 1

f = 270.37 Hz

Step-by-step explanation:

Given that,

The length of the long open end air column, L = 63.8 cm

The speed of sound in the air is 345 m/s

We need to find the frequency of the air column. For an open pipe, the frequency is given by :

`f=(nv)/(2L)\\\\f=(345)/(2* 63.8* 10^(-2))\\\\f=270.37\ Hz`

So, the frequency of the air column is equal to 270.37 Hz.
