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.

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.]
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.
Are silvered surfaces good or poor absorbers of infrared radiation?
Very very poor, they have a tendency of blowing you IP.
Why dark surface is a good emitters of heat?
The dark surfaces heat up faster because dark surfaces attract sunlight faster than light surfaces.
What are good absorbers of light?
Darker colour indicate better absorption of light. Shiny surface is due to it reflect off the light. When the object to totally dark it is because it absorb all the light and transform to heat. You might want to proof it by placing black object and shiny object in the sun, wait few hour and see which object is hotter.

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 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.
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.

Why black bodies are good absorbers of heat?
the color black is a good conductor of heat, so black bodies are good absorbers of heat
What objects do reflect light well?
reflect light well-normally shinysmooth pale colour objects: mirror, glass, shiny metal, tin foil...these objects favour a good image due to the reflection of light is regular do not reflect light well-usually rough, matt , dark colured objects: tree trunk, car wheel, dark carboard, brick, stone, dark opaque plastic... These objects diffuse the picture or do not giva a picture at all because reflected light is irregular.
What type of surfaces reflect thermal radiation?
First of all this is a physics question, not a chemistry question. Silvery surfaces are very good at reflecting heat radiation, dark/dull surfaces attract and absorb heat radiation.
Are reflectors or absorbers good for keeping cold?
it's reflectors.....
