Basic Electromagnetic Wave Properties - Electromagnetic radiation is characterized by a broad range of wavelengths and frequencies, each associated with a specific intensity (or amplitude) and quantity of energy.
The electromagnetic waves with shortest wavelengths are called gamma rays. The electromagnetic spectrum runs from radio waves (the longest wavelength) to gamma waves (the shortest wavelength). In increasing wavelength order, the electromagnetic spectrum is: radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays. In the visible spectrum, violet light has the shortest wavelength.
