What else can I help you with?
Are black surfaces are good reflectors of infra red radiation?
No, black surfaces are actually poor reflectors of infrared radiation. They absorb more infrared radiation compared to other colors, which is why black objects often feel warmer in sunlight. White surfaces are better reflectors of infrared radiation.
Is dull black a good emitter?
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.
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 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.
What are the good reflectors of sound?
Materials such as glass, water, concrete, and metal are good reflectors of sound due to their dense and solid properties that allow sound waves to bounce off easily. Additionally, smooth and hard surfaces tend to reflect sound better than soft and absorbent surfaces.

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)
What surfaces are good reflectors of infared radiation?

Objects that are good reflectors of light?
Some good reflectors of light include metals like silver, aluminum, and copper, as well as materials with a smooth and shiny surface such as mirrors and glass. These materials are able to reflect light due to their high reflectivity and smooth surfaces.
Are reflectors or absorbers good for keeping cold?
it's reflectors.....
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.]
What are good reflectors for solar cookers?

Is black a good conductor of heat?
Dark (especially black) surfaces absorb infra-red well. White and silver surfaces reflect radiation.so its a good absorber. However,conductivity depends on the metal being used.
