The time required for the sound wave to ...

The time required for the sound wave to reach up to the closed end of a pipe filled with air medium is 0.02s. What will be the frequency of vibration of air column ?

20Hz

12.5Hz

10Hz

15Hz

Text Solution

Verified by Experts

The correct Answer is:

`n_1 = (v)/(4l) = (1)/(4t) = (1)/(4xx0.02) = (1)/(0.08)`
=12.5Hz
