      The EM waves of near spectra, UV and IR, are commonly often referred to as ‘light’ as well. Wikipedia even states:

      In physics, the term “light” may refer more broadly to electromagnetic radiation of any wavelength, whether visible or not. In this sense, gamma rays, X-rays, microwaves and radio waves are also light.

      Which fits to my perception of physicists, where in astronomy every element starting at Lithium is referred to as ‘metal’.
