Light may serve well as a 17th century explanation or approximation of what microwaves are. But just to clarify: they are radio waves with no particles. And not only is there no source of heat visible, there literally isn’t one in the device. The heat emanates from the water in the food itself.
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?
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]
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.
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!
Just to clarify myself, I am aware of both of the points you made - that not all types of electromagnetic radiation are created equal, and that it is the interaction of microwaves with water thar creates heat, not the microwave itself, which is essentially just a radiation emitter/container
My language was deliberately pointing out how absurd it would sound to someone from the 17th Century.
This doesn’t make sense as in quantum mechanics, waves and particles are the same. Microwaves consist of photons just like any other type of lightwaves.

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

Don’t know why they didn’t just say EMF or electromagnetic radiation when correcting me, would’ve been a better descriptor

Yeah. It is quite the myth.
A microwave is essentially just an emitter and container.
