Electromagnetic waves have many different varieties, and you might be wondering how we even came to discover such a mysterious and largely invisible force that powers our world. In this lesson, learn about the Doppler effect and how to calculate the frequency of sound produced by a moving source. Electromagetic waves are vibrations created by an interaction between an electric field and magnetic field, and are used to transmit radio waves and wireless signals. An electromagnetic wave can be created by accelerating charges; moving charges back and forth will produce oscillating electric and magnetic fields, and these travel at the speed of light. Radio waves have the longest wavelengths in the electromagnetic spectrum. James Clerk Maxwell derived a wave form of the electric and magnetic equations, thus uncovering the wave-like nature of electric and magnetic fields and their symmetry. Because the speed of EM waves predicted by the wave equation coincided with the measured speed of light, Maxwell concluded that light itself is an EM wave. This ability to manifest electromagnetic waves in their visible form led the introduction of Hertzian waves.
