To further prove my point, you have a black car and a white car out in
the sun on a hot day.
You know the black car is going to be hotter, but why is this when black
is apparently such a good radiator that it should just radiate all that
excess heat right out of that car, as quick as its absorbing it?.
Because its not a good radiator, but it pretty good at absorbing the
sunlight radiated heat increasing the temperature within. The surface
temperature is damn hot and when you drive the black car down the road,
the air passing over the car cools it down due to COVECTION.
Things don't radiated of their own accord without a energy source, and
there is a colour spectrum for different types of radiation, ie: infra
red which you see from the 3-500z is radiated heat, white light
composing all the colours within of various luminous wavelengths. Ultra
violet etc, the list goes on.
Please let me know what the wavelength is of radiated heat from black?
convection
the act of conveying or transmission; specifically, transmission of heat
in a liquid or gas by circulation of heated particles
