What electromagnetic radiation has the shortest wavelength?
Gamma Radiation has the shortest wavelength.
Order is as follows (shortest to longest wavelength):
Gamma, X-Rays, UV, Visible, Infrared, Microwaves, Radio Waves.
Gamma has the shortest wavelength because it has a higher frequency, meaning more waves in a second than any other radiation, which results in the short wavelength.
Frequency is inversely proportional to the wavelength, and because it has a short wavelength and high frequency it has the most energy out of the rest of the Electromagnetic Radiation Spectrum.
Hope I helped :)
