Answer:

The frequency of the wave is, f = 1 Hz

Explanation:

The half-wavelength of the wave can be found from the successive compression or rarefaction.

This is equal to the successive crest or trough.

The one wavelength is the wave that completes one cycle of vibration.

Therefore, the frequency of the wavelength is defined as the number of such vibrations per second. It is given by the formula

                                    f = 1 /T or v/λ   ( v - velocity of the wave)

                                      =  1 / 1

                                      = 1 Hz.

The unit of frequency is Hertz.

Answer:

Explanation:

In the above mentioned diagram it is shown that 2 compressions and 2 rarefactions are passing through a point in 1 second. Since a longitudinal wave is composed of 1 compression and 1 rarefaction therefore the frequency of the given wave is 2 Hz.
