TIL the designs on the microwave door glass act as a Faraday Cage to block the electrons from the microwaves. The shapes stop the wave from reaching outside the glass, thereby preventing damage to our eyes from looking inside the microwave.

Blocks the photons rather?


Photons not electrons. Otherwise yes. They’re very neat little machines. People used to stand in front of huge microwave antennaes to warm up. Worked exactly the same way.


You can test if you’re Microwave is properly insulated by placing a cell phone inside (Don’t run the microwave with it in there) and trying to call it. Your phone shouldn’t be able to get service in there.


Blocks the wave like properties of photon behavior rather,


My great grand parents had an early microwave from the 1960’s. The door was the wire mesh only and no glass.
