Speed of RF waves and IR waves is same as 3*10^8 m/sSpeed of RF waves and IR waves is same as 3*10^8 m/s
This seems to be a very elementary question with a straight-forward answer which can be found in every introductory physics text. I have not, however, been able to find this basic question on PSE with a straight-forward, well-reasoned, not-overly-complicated answer (or any answer for that matter).
Do we want a collection of elementary questions such as this, if they aren't duplicates, even if the answer is easily found in a text?
