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?

Basically Wifi and Radio work on the concept of a Carrier wave.
They broadcast a regular pattern at a specific frequency (basically imagine a slider going from 1 to 0 to -1 and back again repeating that the number of times per second for the frequency, so say 240hz means 1 to -1 and back again 240 times per second).
On this carrier frequency which your receiver can understand, subtle noise is added which reflects the information that you want to send and later receive.
Your sender and receiver transmit this “noise” over a carrier wave back and forth and are built to understand what the noise means so they can convert t to data (wifi) or audio (radio).
