What Materials which are good absorbers of radiation are also good?
Materials that are good absorbers of radiation are also good emitters of radiation. This is known as Kirchhoff's law of thermal radiation. Good absorbers like black surfaces are also good emitters, while poor absorbers are poor emitters. This is why black objects heat up quickly in the sun and cool down quickly at night.
What are the best absorbers of thermal radiation?
Materials that are dark and matte, such as black paint or carbon-based materials, are effective absorbers of thermal radiation. Additionally, metals like copper and aluminum are good thermal absorbers due to their high thermal conductivity.
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 are absorbers of radiation?
Absorbers of radiation are materials or substances that are capable of absorbing and reducing the transmission of electromagnetic radiation. These materials can include metals, gases, and compounds that absorb specific frequencies of radiation. Absorbers of radiation are used in various applications such as shielding against harmful radiation or in sensors for detecting radiation levels.
Which surfaces are poor radaitors and absorbers of heat?
Shiny and reflective surfaces like polished metals are poor radiators and absorbers of heat. This is because they reflect most of the incoming radiation rather than absorbing it. Absorption and emission of heat are higher in rough, dark, or matte surfaces compared to shiny ones.
What are good absorbers of heat?
Good absorbers of heat radiation are like basically materials which are dark in colour. Because for some reason they tend to absorb more radiation than light coloured materials.
In general good absorbers of electromagnetic radiation are also good?
Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same. This is Kirchoff's Law.

What are water vapor and carbon dioxide in earth's atmosphere good absorbers of?
Water vapor and carbon dioxide are good absorbers of infrared radiation. They trap heat in the Earth's atmosphere, contributing to the greenhouse effect and helping to regulate the planet's temperature.
Which surfaces are poor radaitors and absorbers of heat?
Shiny and reflective surfaces like polished metals are poor radiators and absorbers of heat. This is because they reflect most of the incoming radiation rather than absorbing it. Absorption and emission of heat are higher in rough, dark, or matte surfaces compared to shiny ones.
What are the two ways energy is transferred to absorbers?
Energy can be transferred to absorbers through radiation, where energy is emitted in the form of electromagnetic waves, such as light. Energy can also be transferred through conduction, where heat is directly transferred through physical contact between objects of different temperatures.
What are the two principle absorbers of radiation emitted by earth's suface?
The two main absorbers of radiation emitted by Earth's surface are water vapor and carbon dioxide in the atmosphere. These gases trap heat and contribute to the greenhouse effect, which helps regulate the Earth's temperature.
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.
Why black bodies are good absorbers of heat?
Black bodies are good absorbers of heat because they absorb a wider range of wavelengths of light, including visible and infrared. Their dark color allows them to absorb more light energy, converting it into heat more efficiently than lighter-colored surfaces that reflect more light. This absorption helps black bodies retain heat and warm up quickly in response to radiation.
