I don’t think I was ever taught this but thinking about it it seems like suck a futuristic concept and I wanna know how they both work. Like, how do these things send invisible, intangible signals?

It’s just like light. Some colours of light can go through some things that others can’t. Green light can go through green glass, whereas red light can’t.
What your WiFi is doing is just sending 1s and 0s. It’s switching a bunch of different coloured lights on and off to send numbers, numbers that become everything that your phone or computer need. The more modern standards of WiFi are just using more colours and turning them on and off faster.
