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?

Radio and Wi-Fi signals are types of electromagnetic waves, which are a type of energy that travels through space. Electromagnetic waves are made up of two parts: electric and magnetic fields, which fluctuate together in a certain pattern.
Radio waves are produced by electrical charges that oscillate back and forth on a transmitter, like a radio tower. These electrical charges create changes in the electric and magnetic fields around the transmitter, which then propagate outwards as a wave. When these waves reach a receiver, like a radio or phone, they are detected by an antenna. The antenna converts the changes in the electric and magnetic fields into an electrical signal, which can then be processed into the sound or data that we hear or see.
Wi-Fi signals work similarly to radio waves, but at higher frequencies and shorter wavelengths. Wi-Fi signals are produced by an antenna in a router or access point, which creates radio waves that carry data. These waves are then detected by an antenna in your device, like a laptop or phone, which converts the waves into electrical signals that can be processed by the device’s hardware and software.
So essentially, radio and Wi-Fi signals work by creating and detecting changes in electric and magnetic fields, which propagate through space as waves and can be detected by antennas.
