Accelerating electric charges produce electromagnetic waves around them.
A great variety of radiations are electromagnetic waves: radio waves, microwaves,
radiant heat, visible light, ultraviolet radiation, x rays, and gamma rays.
These wavelengths vary from radio waves, the longest, to gamma rays, the
shortest. In empty space, all electromagnetic waves move at the same speed-
-the "speed of light."

Physical Science: Interactions of energy and matter Grades 9-12, page 180 Electromagnetic waves result when a charged object is accelerated or decelerated. Electromagnetic waves include radio waves (the longest wavelength), microwaves, infrared radiation (radiant heat), visible light, ultraviolet radiation, x-rays, and gamma rays. The energy of electromagnetic waves is carried in packets whose magnitude is inversely proportional to the wavelength. |
