D
Ultraviolet light
Verified step by step guidance1
Recall that the electromagnetic spectrum is arranged by wavelength and frequency, with wavelength decreasing as frequency increases.
Identify the types of radiation listed: Microwaves, Infrared radiation, Ultraviolet light, and Gamma rays.
Understand that microwaves have relatively long wavelengths, followed by infrared radiation, then ultraviolet light with shorter wavelengths.
Recognize that gamma rays have the highest frequency and therefore the shortest wavelength among the options given.
Conclude that gamma rays are the type of radiation with the shortest wavelength in the electromagnetic spectrum from the choices provided.
