Electromagnetic radiation of white light in a prism (optics) which breaks down into several separate colors of light Electromagnetic radiation is a combination of electric and magnetic fields oscillate and propagate through space and carrying energy from one place to another. Visible light is one form of electromagnetic radiation. The theoretical study of electromagnetic radiation called electrodynamic, sub-field of electromagnetism. Electromagnetic waves by Heinrich Hertz discovered. Electromagnetic waves including transverse waves. Any accelerating electric charge emits electromagnetic radiation having. The wire (or panghantar such as antennas) delivers an alternating current, electromagnetic radiation is propagated at the same frequency as the electric current. Depends on the situation, electromagnetic waves can be like a wave or as particles. As a wave, characterized by the speed (the speed of light), wavelength, and frequency. When considered as particles, they are known as photons, and each has energy associated with the wave frequency is shown by the Planck relation E = Hf, where E is the photon energy, h is Planck's constant - 6626 × 10 -34 J · s - and f is the frequency of the wave. Einstein then update the formula becomes Ephoton = hf.
