Photons are just the quanta or particles of electromagnetic radiation, of which visible light is a small portion of the overall spectrum. So you can have photons of microwaves as well, such as in this case. Or photons of X-rays or gamma rays or infrared light or ultraviolet light or whatever. It’s pretty wild actually just how small a section of the EM spectrum our eyes are sensitive to!
