According to what properties are radiations arranged in the electromagnetic spectrum?

Radiations in the electromagnetic spectrum are organized by their energy, wavelength, and frequency because these quantities are intrinsically linked. The energy per photon is E = h f, so higher frequency means higher energy. The wavelength and frequency are connected by c = λ f, so shorter wavelengths correspond to higher frequencies and thus higher energies. Since all electromagnetic waves travel at the same speed in vacuum, sorting by wavelength is effectively the same as sorting by frequency or energy. Colors only describe a portion of visible light and don’t capture the whole range, and photons have zero rest mass, so mass isn’t used to arrange the spectrum.
