Which factors affect emission and absorption of infrared radiation?

Which factors affect emission and absorption of infrared radiation?

The EM radiation emitted or absorbed depends on the material and its temperature. The temperature of the object is decreasing. A hot cup of tea on the table will radiate more infrared than it absorbs, it will give out a net transfer of heat until, on cooling, it reaches the ambient room temperature.

What are the factors affecting solar radiation?

Seven factors affecting solar UV radiation

• Solar elevation. Where the sun sits in the sky determines the level of UV radiation reaching us.
• Ozone. Ozone is an important part of our atmosphere and high levels of ozone absorb higher levels of UV.
• Cloud cover.
• Ground surface reflectivity.
• Altitude.
• Aerosols and pollutants.
• Direct and diffuse UV.

How is radiant energy absorbed?

Solar power harvests radiant energy carried by the light from our sun by converting it into electricity. Plants are able to harness and use light energy in a process called photosynthesis. They absorb radiant energy from sunlight and transform it into useful chemical energy contained in molecules within their cells.

Which colors reflect the most heat?

Black – the color that absorbs all visible wavelengths of light – attracts the most heat, followed by violet, indigo, blue, green, yellow, orange and red, in descending order.

Which colors absorb the most heat?

The more light the object absorbs, the more heat absorbed since light is energy. If you consider it a color, black absorbs the most heat. A black object absorbs all wavelengths of light and reflects none. Objects that are white, on the other hand, reflect all wavelengths of light and therefore absorb the least heat.

What color stays the coolest?

White, silver, and other light colors are coolest, reflecting about 60 percent of sunlight but there are dark “cool” colors that can also stay cooler than traditional dark colors.

What material can absorb the most heat?

Zeolite thermal storage retains heat indefinitely, absorbs four times more heat than water.

What kind of material allows heat to transfer quickly?

conductors
