Are silvered surfaces good or poor absorbers of infrared radiation?
Very very poor, they have a tendency of blowing you IP.
What type of surfaces are good radiators of heat?
Dull black surfaces they are also best at absorbing it as well. [Shiny and silvery or white surfaces are poor radiators and absorbers of heat. However they are very good in reflecting heat radiation.]
Who emits more radiation a white body or a black body?
Good absorbers of radiation are also effective emitters. Thus, a black body, which more readily absorbs infrared radiation also emits it more readily.
Is a good absorber of radiation a good emitter or a poor emitter?
It is a good emitter, as you can not have a good absorber, which isn't a good emitter. Dark, Matt surfaces are good emitters and absorbers e.g. a saucepan.
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.

What are water vapor and carbon dioxide in earth's atmosphere good absorbers of?
infrared radiation
What type of surfaces are good radiators of heat?
Dull black surfaces they are also best at absorbing it as well. [Shiny and silvery or white surfaces are poor radiators and absorbers of heat. However they are very good in reflecting heat radiation.]
Why are carbon dioxide and water vapor called selective absorbers?
Any object that can specifically absorb and emit radiation (in the form of, say, infrared radiation), is called a selective absorbers. An example is: Snow. It is a good absorber of infrared radiation but poor absorber of sunligh. Object that selectively absorb radiation at some wavelength tend to radiate radiation at that same wavelength. CO2 and water vapors are both very good absorber of infrared radiation but at the same time poor absorber of different forms of solar radiation that are visible to us.

Good absorbers of radiation are also effective emitters. Thus, a black body, which more readily absorbs infrared radiation also emits it more readily.

In general good absorbers of electromagnetic radiation are also good?
Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same. This is Kirchoff's Law.
What are good absorbers of heat?
Good absorbers of heat radiation are like basically materials which are dark in colour. Because for some reason they tend to absorb more radiation than light coloured materials.
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.
Are dark surfaces good absorbers?
Yes, they are good absorbers! Since the sun rays are absorbed by the dark surface (such as a shirt), the dark surface would absorb other things as well. For instance gas. Hope this helped! ;)
Why dark surfaces are good absorbers of heat and shiny surfaces are poor absorbers of heat?
If you are talking in terms of the suns heat being absorbed by the surfaces then I have the answer. Shiny surfaces naturally deflect the suns rays where as dark surfaces are easy conductors of heat as they naturally catch the suns rays. You will notice with leather or print on a shirt that it gets hot because the rays have nowhere to go. A shiny surface will just deflect it back.
Why does a firefighter wear a silver suit instead of a black suit?
Sliver surfaces reflect heat keeping the body of the firefighter cool, whereas black surfaces are good absorbers of heat.
