Reply to comment by triffid_hunter in Where do photons go if they've been emitted but are destined to never be absorbed, and would these photons traveling ad infinitum define the edge of the universe (even if space itself were still larger)? by mysteryofthefieryeye

Except microwaves are way higher frequency than radio waves which we detect all the time. So that’s not the answer

Uhh microwave ovens, WiFi, and bluetooth all use the same radio band around 2.4GHz, and the definition of "microwave" is frequencies between 300MHz and 300GHz…

I’m confused with what you’re trying to prove. All those examples (2.4GHz) is within the range 300MHz - 300GHz. So they are microwave frequencies, right?

Yep - I'm confused about /u/bullett2434 saying microwave frequencies are higher than radio frequencies, when the dramatic majority of our radios are using microwaves these days…

Ohhh, I see what you mean. Yeah, it looks like microwave frequencies are a subset of radio frequencies. So that point is confusing me too 😅
