No, dull black is not a good emitter of heat. Black objects typically absorb heat well but do not emit it efficiently. Shiny or polished surfaces are better at emitting heat than dull or matte ones.
A good absorber of radiation is a good emitter. Radiation is the energy that that comes from a source and travels through space or through something. Some examples of radiation include light, heat and sound.
Black is the best absorber and emitter of heat. Black objects absorb most of the incoming radiation, converting it into heat, and they also emit thermal radiation efficiently.
No, black or dull surfaces are not good reflectors because they absorb light rather than reflecting it. Reflectivity is higher in surfaces that are smooth and shiny, such as mirrors or metals.
A dull black surface is a good radiator of heat because it has a high emissivity, which means it can efficiently emit thermal radiation. This is why black surfaces are commonly used for radiators and heat exchangers to improve heat transfer.
Dull black surfaces are considered good emitters or absorbers because they have a high emissivity, which means they can both absorb and emit radiation efficiently. The rough surface of a dull black object traps more light and heat than a smooth surface, allowing for efficient absorption and emission of energy.
It is in fact the best radiator. Dull black is the best absorber and emitter. Then shiny black, followed by white, then silver. While the best reflector goes the other way around (silver's the best, then white, followed by shiny black, then dull black)
because its a good emitter/absorber of radiation

Generally, dull black
An object is a good emitter of radiation if it is a good absorber of radiation.
Because the colour black is a good emitter of heat and therefore emits the heat away from the fridge since you would want the fridge to be cold.

Black is known as a dull color. Death is dull and a grieving time, therefor black is mostly used with mourning
Shiny black
