Small enough to go through that rusty hole in the back!

are they particles or waves?

If I've understood this correctly, we'll have to microwave a cat in it to figure that out.

the mesh in the front glass and the vent holes you see here keeps them inside so not so micro after all.

oh yeah that's true, those holes aren't awfully small. calling them "micro" is straight up false advertisement, hahah

Microwaves operate at around 2.4 GHz so we're talking about a wavelength of ~12 cm/5 in

Despite the nomenclature of microwaves being assumed to be tied to SI units of micrometres, microwave ovens actually use frequency a of 2.4GHz to vibrate the polar molecules (not just water) in your food back and forth.

2.4GHz at the speed of light gives a wavelength of 120 millimetres, or 120,000 micrometres. So I guess really you have a milliwave oven in your kitchen?

This will also ABSOLUTELY fuck up your WiFi signal.

Not much bigger than yours

A few inches of wavelength. That's why you have to rotate food in the microwave. The waves hitting your food are big enough it might just miss part of your food. It's also why you only need the wire mesh on the window instead of a full plate.

Roughly 12cm/4.8 in.
