The visible light portion of the Sun's spectrum. Our eyes can only see a small section of the complete electromagnetic spectrum. Visit NoirLab to download a larger version of this image. N.A.Sharp, NOAO/NSO/Kitt Peak FTS/AURA/NSF Normal, white light is actually made up of a rainbow of different colors, from red and orange to blue and purple. There are many other "colors" of light that we cannot see. These include ultraviolet (UV) and infrared (IR) "light" that is just beyond the range of human vision. They also include more exotic forms of radiation such as X-rays, gamma rays, and radio waves. Together, all of these different "colors" of light are called the electromagnetic spectrum, or EM spectrum for short. Each section of the electromagnetic (EM) spectrum has characteristic energy levels, wavelengths, and frequencies associated with its photons. Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation. In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves. Microwaves (like the ones used in microwave ovens) are a subsection of the radio wave segment of the EM spectrum. © 2017 UCAR with portions adapted from Windows to the Universe (© 2005 NESTA) Open in App Solution The electromagnetic spectrum is the range of all the types of electromagnetic waves arranged according to wavelengths or frequencies. Radio waves have the longest wavelength in the electromagnetic spectrum. (adsbygoogle = window.adsbygoogle || []).push({});Similar questions Q.

Name the radiation which has longest wavelength? Q. Write the name of the radiations of shortest and longest wavelength in the electromagnetic spectrum. Q. Which of the following electromagnetic waves has the longest wavelength? View More Which electromagnetic has the longest wavelength?Radio Waves -- The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves.
Which electromagnetic wave has the shortest wavelength?Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies.
Which wave has a longer wavelength?The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.
