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.

they are non-matter

explanation:

they are non-matter. basically, any type of energy or any abstract concept is an example of something that does not matter. other examples include dreams, magnetism, radio, and hate

the motion of a pendulum is a classic example of mechanical energy conservation. a pendulum consists of a mass (known as a bob ) attached by a string to a pivot point. as the pendulum moves it sweeps out a circular arc, moving back and forth in a periodic fashion.
