For convenience sake let’s say you have 2 identical lasers, one is blue and one is red. And you shine it on lead (so none of the light leaks through) until the lead doesn’t heat up anymore. Would the temperature change at all between the different color lasers. It doesn’t have to be red or blue, it could be microwave or x ray, just different colors is nessisary.

      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’.
