What is the frequency of this wave? 1234

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: the rock sample is a sedimentary rock.

explanation:

it is given that:

mass of rock sample, m = 2.7 g

volume of rock sample,

so, density of rock sample will be

since, the density of rock sample is . hence, the rock sample is a sedimentary rock, whose densities varies between .
