Although it is somewhat redundant, we reproduce here still another plot of the EM Spectrum, with added items that are self-explanatory: At the very energetic (high frequency and short wavelength) end are gamma rays and x-rays (whose wavelengths are normally measured in angstroms [Å], which in the metric scale are in units of 10 -8 cm). Radiation in the ultraviolet extends from about 300 Å to about 4000 Å.
