Answer» Electromagnetic radiation (EMR) is a kind of radiation including visible light, radio waves, gamma rays, and X-rays, in which electric and magnetic fields vary simultaneously. It consists\xa0of self-sustaining oscillating electric and magnetic fields at right angles to each other and to the direction of propagation. EMR does not require a supporting medium and travels through empty space at the speed of light.
