What surfaces are better absorbers and emitters of thermal radiation?
Dark matt surfaces absorb heat radiation falling on them much better than bright glossy surfaces, such as gloss white or silver. They also emit much more heat radiation (at any given temp.)
Which surfaces absorb heat?
All surfaces absorb some heat.
What is the difference between the way black and white surfaces affect light?
White surfaces reflect light and heat. Black surfaces do not reflect light and they absorb heat.White surfaces reflect light and heat.

Black surfaces do not reflect light and they absorb heat.
What material is best absorbed of infra-red radiation?
skinny metal
What types of surfaces absorb heat?
Dark, rough, and/or porous surfaces absorb the most heat (ex. Asphalt)
How does the type of surface affect heating by radiation?
Dark matt surfaces absorb radiated heat much more easily than light-coloured shiny surfaces.
What type of surfaces absorb sound?
a solid surface
What surfaces are better absorbers and emitters of thermal radiation?
Dark matt surfaces absorb heat radiation falling on them much better than bright glossy surfaces, such as gloss white or silver. They also emit much more heat radiation (at any given temp.)
Why does soil absorb more solar radiation than grass?
Darker surfaces like soil absorb more than lighter ones like grass do.
What property of dark surfaces enable them to absorb heat radiation?
"dark" implies that the object does not reflect light very well - thus it must be absorbing radiation.
Which surfaces absorb heat?
All surfaces absorb some heat.
Why do white surfaces stay cooler than dark ones?
White surfaces reflect infrared radiation (which includes light and heat), while darker/blacker surfaces absorbinfrared radiation. As a result, lighter/whiter surfaces will be cooler because they reflect heat, and darker/blacker surfaces will be warmer because they absorb heat. The amount by which a surface reflects (or absorbs) infrared radiation is referred to as albedo and is usually expressed as a value between 0 (no reflection) and 1 (perfect reflection).

Which layer of the atmosphere does not absorb solar radiation?
Troposphere does not absorb solar radiation. All other layers do not absorb.
What material is best absorbed of infra-red radiation?
skinny metal
Why does something shiny stop heat radiation?
Types of light energy are reflected off of shiny surfaces back into the atmosphere. Other surfaces, such as darker ones, absorb the light energy and heat up much quicker.
What types of surfaces absorb heat?
Dark, rough, and/or porous surfaces absorb the most heat (ex. Asphalt)
