Question

What is the frequency of this wave?

can someone pls explain and answer ​

Answer 1

f = 1 Hz

Step-by-step explanation:

From the attached figure, we find that the time period of the wave is 1 second.

It is a longitudinal wave. It travel in the form of compression and rarefaction. The relation between time period T and frequency f is given by :

`f=(1)/(T)\\\\\text{As T = 1 s}\\\\f=1\ s^(-1)\\\\=1\ Hz`

Hence, the frequency of this wave is 1 Hz.
