Eli5: What component in eletonics like cellphones and computers actually “receives” and “emits” wifi signals? What is wi-fi in terms of physics?
In: Physics
In terms of physics, Wifi is exactly the same stuff that your microwave uses to heat up food…microwaves. Same frequency too. Wifi devices just use way less power making them safe. Microwaves are a frequency of electromagnetic radiation also known as light which have less energy than what is needed for us to be able to see them.
