What surfaces best absorb infrared radiation black white or red?
Black surfaces best absorb infrared radiation because they absorb a wider range of wavelengths compared to white or red surfaces. White and red surfaces tend to reflect more infrared radiation due to their higher albedo, making them less effective absorbers.
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 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.
Who emits more radiation a white body or a black body?
A black body emits more radiation than a white body. A black body absorbs all radiation that falls on it and re-emits it as thermal radiation, making it an ideal emitter. On the other hand, a white body reflects most radiation and thus emits less overall.
What surfaces are slow to emit infrared radiation?
Surfaces that are good insulators, such as wood, plastic, and ceramics, are slow to emit infrared radiation compared to metals and other good conductors. This is because insulating materials trap heat and release it more slowly.
What material is the best absorber of infra red-radiation?
white paper

Absorption of infrared radiation in the skin?
Infrared radiation penetrates through the tissue and is also absorbed by different molecules. It is strongly absorbed by certain pigments and blood which determine the skin color, the multi-colored irises and the white of our eyes.
Is snow ever any color other than white?
yes it is it can be many colors, yellow blue, red, white, violet, green and orange because of infrared radiation.

Explain as completely as possible why the asphalt was so much hotter than the concrete?
The concrete, being nearly white, reflected much of the Sun's infrared energy, while the asphalt, being black, absorbed much of the Sun's infrared energy. (Infrared radiation is associated with heat.)
How are eletromanetic waves produced?
Well there's many ways. One is from the sun's electromagnetic waves that have infrared radiation, white light (which is all colors of the rainbow), and ultraviolet radiation in case you wanted to know more about them.
Which emits the most infra red radiation matte silver surface or shiny black surface?
Matte (dull) and black surfaces emit infrared radiation at a faster rate than shiny and white surfaces.
Which material is best absorber of infra red radiation?
the best absorber for infared radiation is a white shinny absorber :) ,,, im going to give you a energy effinency is,, the effenciey of any applliance is never more than 100 percent, the amount of energy transfered by a 4kw kilowatt)appliance switched on for 15 mins is 1 kw. if the cost of using this energy is 10p, then one kwh is the exact same cost as the same amount of 1kw. to convert watts in kilowatts, is you should divide by 1000!

Experiment to show that a dark surface is a ggod absorber of radiation while a white surface is a bad absorber of radiation?
Paint two otherwise identical objects, one with white paint, the other with black paint. Put both of them in the sunshine. The black object should get hot faster than the white one, because the absorbed heat energy gets converted to heat.
