Yes, it is. As dull and black surfaces are the best emitters as well as the best absorbers of radiation.

Hope my answer is good enough to be stand up your question needs.

BEcause they contain an internal deficiency which causes the black surface to emmit unnecessary radiation.

Black does not reflect any colour of light. The light (and other invisible forms of electromagnetic radiation) is absorbed by the surface and generally converted to heat.

The same surface as is a good absorber is also a good radiator: a black surface that is not reflective.

This is where the term "black body" comes from.

This is related to the fact that a good emitter must needs also be a good absorber.

Black surfaces absorb heat. White surfaces will reflect (radiates) heat.

Yes. If an object is good at absorbing heat, it will also be good at emitting heat.

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)


Is white surface good radiator of heat?

A white surface is a good radiator of heat.


Why are the inner surface of a solar cooker painted black?

for it to absorb heat because dull colors are good absorbers of heat


Is the good radiator of heat a shiny silvered surface or white surface?

Shinny silverd surface


Why is cooling fins painted dull black?

A black body radiates more heat than any other. Therefore if you want to lose heat, paint it black (unless of course it is in the sun where the black paint might have some heat absorption properties for unrelated reasons.)


What is the difference between a good radiator of heat and a good reflector of heat?

heat absober absorbs heat & refelector reflect it


What material is a radiator made of?

Material with low specific heat capacity and with blackened surface are good for radiators.


Why does a good absorber of radiant energy appear black?

In short, because they "don't reflect'." A matte surface isn't smooth; it has a surface that does not fully reflect light/radiation; the surface looks dull because there's little reflection. A smooth surface will reflect because it's smooth (glass-like) and will reflect or bounce light away from its surface. The surface looks shiny because of the reflection. The color of the surface matters because the darker the color, the more light/radiation is absorbed. Lighter colors reflect light; darker colors absorb light.


Descrtbe an experiment to prove that dull colours are good absorbers of heat?

Requirements: 2 thermometers, black paint Procedure: Paint 1 of the thermometers black and do not do anything with the 2nd one. Keep both thermometers in sun for an hour or two. After an hour record the temperature of both thermometers you will find that the one painted black shows more temperature as compared to the second. Conclusion: Dull colours are good absorbers of heat.


What might be the effect of sprinkling black soot over the ice in the Arctic or the Antarctic?

The ice under will melt because black is a good absorber and a poor radiator.


Which is the better reflector of light a black surface or a white surface?

A white surface because black absorbs the light, while white while reflect it. A good experiment is to wear a black shirt outside and a white shirt outside and see which makes you hotter in the sun


Why drain pipes are always painted black?

black is a good absorber and hence a good emmiter of thermal energy. painting the surface black can increase the rate of this transfer of energy, and hence thedrain pipes are painted black:)
