TIL - But where can I learn more? Is this a mostly classic effect (heat/shockwave) or mostly quantum level?
- mnw21cam 4y agoA combination. The reason the CO2 absorbs that particular wavelength of IR light is deeply bound in quantum processes. But the reason they hum is simply a classic heat effect.
