electromagnetic wave
An "electromagnetic wave" is a wave, which consists of an oscillating electric and magnetic fields perpendicular to each other, to the propagation direction. The wave travels in a space at the velocity of light (300,000 km/s). If we list electromagnetic waves in order of wavelength, radio waves have the longest wavelength, followed by infrared rays, visible light rays, ultra-violet rays, X-rays, and gamma rays.
