I’ve read articles which bring up concerns about how crowded the radio frequences are and how we have to keep using new regions. But I don’t understand why the frequences get filled up. It seems like there should be infinite frequencies in any range.
For example, my FM radio has stations like 99.5 and 99.7 MHz. That’s 99,500,000 and 99,700,000 Hz, right? Why couldn’t they use any number of frequencies between that range like:
I mean, it’s not like there are only 200,000 frequencies between 99.5 and 99.7 MHz. There are infinite frequencies. So how do we run out of them?
