The electromagnetic spectrum is the range of energy waves of various wavelengths—from the very short gamma and X-rays, through longer ultraviolet, visible, and infrared light, to microwaves and very long radio waves.

The electromagnetic spectrum is the range of traveling waves of energy that run from very short gamma and X-rays through ultraviolet light, visible light, microwaves, and out to long radio waves.

A laser fires a light beam. Before the laser, scientists developed a similar device: a maser which stands for Microwave Amplification by Stimulated Emission of Radiation. A maser is basically a microwave version of the laser. Microwaves are a form of electromagnetic radiation similar to, but shorter than, radio waves. The best-known use of masers is in highly accurate clocks.
