I hope you will now realise that you are wrong, will apologise
and admit your mistake. Cold radiation does exist.
Cheers, Alastair.
There is no such thing in Physics as "cold" - just lack of heat.
I am not saying "cold" exists. I am saying "cold radiation" exists,
in the same way cold water exists.
No. You are talking about the human experience of temperature. We are
trying to explain to you how physicists, engineers, scientists talk
about heat.
(do you really have an engineering degree? - I find that hard to believe
- what was it in?)
If your hands feel extremely cold and you put them in 'cold' water from
your tap you may 'feel' the water as 'warm. Conversely if you feel
extremely hot and you put your hands in water at the same temperature
you would feel it as 'cold'.
The temperature of the water hasn't changed.
The point of science is to use definitions and talk precisely. Why can't
you accept this. Scientists don't talk about cold radiation. Are gamma
rays 'hot radiation' or just photons with a specific frequency/energy?
