Heat mirrors has been there for a long time, especially in our lifetime. Pp used it to cook food in Africa, especially at Red Cross Concentration Camp. LOL.

Infrared radiation takes up a certain spectrum in the EM Spectrum, so it has a range of frequency, not just one particular value.
"Say you're in a [chemical] plant and there's a snake on the floor. What are you going to do? Call a consultant? Get a meeting together to talk about which color is the snake? Employees should do one thing: walk over there and you step on the friggin� snake." - Jean-Pierre Garnier, CEO of Glaxosmithkline, June 2006

Right, I know it has a range, but does the vibration of molecules fall into the same range, or does it spill over into other ranges?

So lets say I light a candle. How would I measure the frequency of the IR coming out of it, and would it vary like crazy or be one specific value? Is the frequency a function of how "hot" the heat source is?
