Is a good reflector of radiation a good emitter of radiation?
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.
Which color is the best absorber and emmiter of heat?
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.
Are black or dull surfaces good reflectors?
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.
Is dull black surface is a good radiator of heat?
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.
Why are dull black surfaces considered good emitters or absorbers?
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.
Is dull surface a good radiator of heat?
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)
Why does a black colour absorb more heat?
because its a good emitter/absorber of radiation

What absorbs more heat-shiny black or dull black?
Generally, dull black
An object is a good emitter of radiation if it is what?
An object is a good emitter of radiation if it is a good absorber of radiation.
Why is the black of a refrigerator painted black?
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.
Why are dull black surfaces considered good emitters or absorbers?
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.
Why is black the color of mourning?
Black is known as a dull color. Death is dull and a grieving time, therefor black is mostly used with mourning
Which reflects heat shiny black or dull black?
Shiny black
