Maybe I’ve forgotten my high school physics, but radio waves and light are still all EMF, right? They’re the exact same thing at different frequencies?
Yes. Microwaves are called that because they have a wavelength in the order of magnitude of micrometers, while visible light has wavelengths of 380-750 nanometers.
That’s what I thought as well. A quick Wikipedia read more or less confirms this.
In physics, electromagnetic radiation (EMR) consists of waves of the electromagnetic (EM) field, which propagate through space and carry momentum and electromagnetic radiant energy.[1] Types of EMR include radio waves, microwaves, infrared, (visible) light, ultraviolet, X-rays, and gamma rays, all of which are part of the electromagnetic spectrum.[2]
I must have forgotten my high school physics, maybe because it was too long ago but I thought light is the only kind of EM radiation with photons. Guess I learned something today. Thanks!

Yeah, they are. Just two different types, or frequencies rather
