the nano structur material are good absorber as compared to bulk and microsized material
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.
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.
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 light include black surfaces, such as black paper or fabric, as well as materials with dark or matte finishes. Pigments like carbon black or graphene can also absorb light effectively. Metals like gold and silver can also absorb light, particularly in the visible range.
Materials that are good absorbers of microwaves include water, certain plastics, ceramics, and some types of food. These materials are able to absorb and convert microwave energy into heat due to their molecular structure and composition. Metals, in contrast, are poor absorbers of microwaves and reflect them instead.

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.

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.
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.
Poor absorbers of heat radiation include materials that are light in color, shiny, or reflective, such as aluminum foil or white paint. These materials do not easily absorb heat energy from radiation and may instead reflect it away.
it's reflectors.....

Shock absorbers are typically made of a combination of metal components (such as steel) and rubber or polyurethane materials. The metal components provide durability and support, while the rubber or polyurethane materials help absorb and dampen the impact and vibrations from the road.
