What surfaces are good absorbers of infrared radiation?
Surfaces that are dark, rough, and opaque are good absorbers of infrared radiation. Materials like asphalt, concrete, and vegetation are examples of surfaces that absorb infrared radiation effectively.
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.
Are shiny surfaces poor absorbers and poor emitters for infra-red radiation?
Shiny surfaces are poor absorbers of infrared radiation because they reflect rather than absorb it. However, they can still be good emitters of infrared radiation if they are close to being perfect blackbodies. The reflectivity of the surface plays a significant role in determining its emissivity for infrared radiation.
Are silvered surfaces good or poor absorbers of infrared radiation?
Silvered surfaces are poor absorbers of infrared radiation. They have low emissivity in the infrared spectrum, which means they reflect rather than absorb infrared radiation. This property makes them useful for applications where minimizing heat absorption is desired.
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.

Why are dark surface good absorver of inferate radiation?
Terms used are not apt. It is not dark, it is BLACK Not aborver but ABSORBER It is not inferate. It has to be INFRA RED Black itself means absence of radiations. So it has to be ready to accept anything falling on it. Hence the result
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.]
How hard surfaces Emmit and absorb radiations?
Hard surfaces like glass, metal, and concrete are generally good at reflecting radiation, especially in the visible light and near-infrared spectrum. However, they can also absorb some of the radiation, depending on their composition and properties. The absorption and emission of radiation by hard surfaces are influenced by factors such as color, texture, and temperature.
Is the earth a good absorber and good radiator of heat?
Yes, the Earth is a good absorber of heat, with its atmosphere and surface absorbing solar radiation. It also radiates heat back into space in the form of infrared radiation, making it a good radiator of heat. This process is essential for maintaining Earth's energy balance and regulating its temperature.
What sort of radiation absorbs or reflect radiation?
It doesn't absorb clever. It penetrates, and it can penetrate paper, smoke, a layer of skin and thin aluminium.
What metals reflects electromagnetic radiation?
Metals such as aluminum, silver, and gold are known to be good reflectors of electromagnetic radiation, including visible light and infrared radiation. Their smooth and shiny surfaces allow for efficient reflection of a wide range of electromagnetic wavelengths.
What are the surfaces that are the best at absorbing radiation?
Surfaces that are dark in color and rough in texture tend to be the best at absorbing radiation. These surfaces absorb a wider range of wavelengths and do not reflect as much radiation as smoother, lighter surfaces. Materials like asphalt, tar paper, and black rubber are good examples of surfaces that absorb radiation well.
