Yes, Good absorber of heat are good emitters of heat. And in both the way rate is same.
This is Kirchoff's Law.

Is electromagnetic radiation made of photons or the perpendicular oscillation of magnetic and electric fields?
Electromagnetic radiation (EMR) is the oscillation and movement of magnetic and electric fields which are perpendicular to each other. This is the way in which electromagnetic radiation is propagated. Photons are another term for higher energy EMR, and it could also be argued that photons make up some forms of electromagnetic radiation.
What part of the electromagnetic spectrum can be sensed without technology?
We have detectors on our bodies to detect electromagnetic radiation that we refer to as 'light',and also radiation in the far infrared that we refer to as 'heat'.A lot of people think we're also able to detect EM radiation in other bands, but scientific experimentationdoesn't support that.Yet ? ~ ~ oooweeeooo ~ ~ ~ ~
What absorbs ultraviolet radiation?
Ozone does as done carbon black and special chemicals - UV absorbers such as benzotriazoles and others also.
Is grilling a radiation?
A grill that cooks meat gives off electromagnetic radiation, both visible and infra-red. Some of the cooking is also done by convection.
Does electromagnetic radiation include only visible light waves?
Not exactly. Actually, no. Photons are chunks of electromagnetic waves. As such, they do not produce EM waves, they ARE those waves. A photon inter-acting with some other particle could result in other photons -- ie, a different kind of EM wave -- being created.
What is transferred by electromagnet waves?
Electromagnetic radiation is transferred by electromagnetic waves. Electromagnetic radiation is a fundamental phenomenon of electromagnetism.
Who emits more radiation a white body or a black body?
Good absorbers of radiation are also effective emitters. Thus, a black body, which more readily absorbs infrared radiation also emits it more readily.
What does electricity cause?
electricity causes an electromagnetic field, also radiation.
Is radiation the direct transfer of energy by electromagnetic?
It's the emission of electromagnetic energy from something, not the transfer. That em-radiation could travel for ever across the universe, never interacting with anything ever again and it would still be radiation.________________________________________________________Not all radiation is electromagnetic engery. Electromagnetic energy is transfered by way of photons. Photons are emited through gamma radiation and black body radiation. Nuclear decay of alpha particles and beta particles (which are also considered radiations) are actual particles that have mass, and are not electromagnetic radiation.

Which is the only kind of nuclear radiation that is also an electromagnetic wave?
The gamma wave is.
Wave that can travel through an empty space?
what is a form of energy that travels as waves through the air and some solids and liquids call?
Can heat energy also be light energy?
Yes. Heat energy is a form of electromagnetic radiation, like infrared Radiation.
The full range of energy in sunlight can best be described as?
The full range of energy in sunlight can best be described as electromagnetic radiation. Electromagnetic radiation behaves as waves and also as particles called photons.
Are cerenkov radiation harmful?
Cerenkov radiation is also spelled as Cherenkov is an electromagnetic radiation that comes for particles as they travel at speeds greater that the speed of light. The radiation if seen is often blue and is not harmful.
Does laser belongs to group of radiation?
Technically, yes. A laser is a concentrated beam of monochromatic (usually) light. Given that light itself is considered to be part of the electromagnetic spectrum and that that spectrum is referred to as electromagnetic radiation (as it doesn't need a medium to travel through) then one could deduce that a laser beam is radiation. In addition, gamma radiation also forms part of the electromagnetic spectrum.
