Electromagnetic Radiation is energy in the form of a Wave of oscillating electric and magnetic fields, the wave travels through a vacuum at a velocity of 2.998 x 10^8 meters per second (186,284 miles per second). The Wavelength of an Electromagnetic wave determines its properties , x-rays , infrared , microwaves , radio waves and light are electromagnetic radiation.
