Yes, according to Kirchhoff's law of thermal radiation, good absorbers are good emitters of radiation at a given wavelength. This means that materials that efficiently absorb incoming radiation also emit radiation effectively at the same wavelength.
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.
Good absorbers are good emitters because they efficiently absorb energy from their surroundings, which in turn allows them to emit energy at a similar rate. This equilibrium is established based on the material's ability to absorb and emit thermal radiation effectively.$arity This principle is known as Kirchhoff's Law of Thermal Radiation.
Dull black surfaces are considered good emitters or absorbers because they have a high emissivity, which means they can both absorb and emit radiation efficiently. The rough surface of a dull black object traps more light and heat than a smooth surface, allowing for efficient absorption and emission of energy.
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.
Well, honey, let me break it down for you. A good absorber of radiation is also a good emitter. It's like a give and take relationship - what goes in, must come out. So, if something sucks up radiation like a sponge, you can bet your bottom dollar it's gonna spit it back out just as well.

Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same. This is Kirchoff's Law.
Good absorbers of radiation are also good emitters because they can absorb energy from their surroundings and then emit that energy in the form of radiation. This is governed by Kirchhoff's law, which states that objects that absorb radiation well at a specific wavelength are also good emitters at that same wavelength.

good conductors are better emitters

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.]
no!
Materials that are dark, rough, and thick tend to be good absorbers of heat, such as black metal or asphalt. In terms of sound, soft and porous materials like foam, carpet, or curtains are good absorbers.
