Gamma-rays have the shortest wavelength of any type of radiation. The electromagnetic spectrum contains microwaves, radio waves, infrared waves, optical waves, ultraviolet rays, X-rays and gamma rays.Continue Reading
Electromagnetic radiation contains wavelengths of different sizes, ranging from large radio waves that can be longer than a football field to tiny gamma rays that can be smaller than the nucleus of an atom. Electromagnetic radiation is also measured in energy and frequency.
Scientists measure the wavelength of radiation from one wave crest to another. Electromagnetic waves are found in a number of different objects throughout the home. This type of radiation is common in microwaves, televisions and radios.Learn more about Optics & Waves
