The electromagnetic frequency of a wave is defined as how many times the peak of this oscillation moves past a point each second. This has a major effect on the properties of the wave, including its energy.
EMF stands for Electromagnetic Field. EMF is one of the four fundamental forces of nature. All matter, living or nonliving, produces electromagnetic radiation. The various manifestations of electromagnetic radiation share one fundamental property: the electric charge.
