Hi all: Why is it that we have a dozen or so different electromagnetic wave types and yet every one of them can be used for analog and digital communication?
Thanks!

The electromagnetic spectrum is continuous, we broke them up into “types” based on how different frequencies behave because it makes handling and discussing the concepts easier.
They all share the property that if you can emit and receive them in a structure way they can be used to communicate data. Thats as true for using visible light morse code as it is for high speed microwave transmissions. Digital vs analog is really just about how the emit/receive portion of that is happening, in particular the encoding and decoding of that data on either end.
