If you know that a surface is a good absorber of energy what can you infer about its ability to radiate energy?

Yes.
As for the reasons, one of them is that if this were not so, the Second Law of Thermodynamics would be violated, because two side-by-side objects, one black, one white, would develop a temperature difference.

∙ 15y agoYes, the best is a black body. It absorbs all the incident radiation, and emits the maximum possible for a body at the temperature of the body. In fact the energy emitted per unit area is a constant times the absolute temperature to the fourth power (Stefan's Law), and for a black body the constant is 5.7 x 10-8 Watts/sq meter. For a non-black body another factor less than 1 has to be introduced, the emissivity.

∙ 13y agoI would say *yes*. This is Kirchoff's law, which states that absorptivity=emissivity in all cases.

∙ 10y agodull , black surfacesare good radiators and absorber of heat
Wiki User
∙ 7y agoYes; if a substance absorbs radiant energy well, it will also emit radiant energy, better than a substance that doesn't absorb radiant energy so well.

∙ 12y agoIt will also be a good radiator!!
Wiki User
∙ 13y agoYes, always. This is Kirchoff's law.

Does a drum set radiate sound energy?
Yes, a drum set can radiate sound energy when the surface of the drum vibrates on striking it to set particle molecules in air to transfer energy in a wave form and radiate out.
The pupil of your eye is a net absorber of radiant energy a net emitter of radiant energy neither a net absorber or emitter of radiant energy?
A net absorber of radiant energy.
What objects can radiate energy?
All objects radiate energy at a rate depending on their temperature.
Why does a good absorber of radiant energy appear black?
In short, because they "don't reflect'." A matte surface isn't smooth; it has a surface that does not fully reflect light/radiation; the surface looks dull because there's little reflection. A smooth surface will reflect because it's smooth (glass-like) and will reflect or bounce light away from its surface. The surface looks shiny because of the reflection. The color of the surface matters because the darker the color, the more light/radiation is absorbed. Lighter colors reflect light; darker colors absorb light.
When light is absorber light energy is transformed into stored energy true or false?
true
Does a drum set radiate sound energy?
Yes, a drum set can radiate sound energy when the surface of the drum vibrates on striking it to set particle molecules in air to transfer energy in a wave form and radiate out.
What is the strength of a beta particle?
The strength of a beta particle is its ability to cross the absorber to reach the detector.Now the strength of a beta particle depends upon the energy of the beta particle and thickness of the absorber.
The pupil of your eye is a net absorber of radiant energy a net emitter of radiant energy neither a net absorber or emitter of radiant energy?
A net absorber of radiant energy.
If Earths surface is heated does it radiate most of the energy back into the atmosphere as ultraviolet radiation?
No. It radiates most energy back as infarred radiation.
If a red star and a white star radiate energy at the same rate can they be the same size If not which must be the largest Why?
They cannot be the same size. The red star must be larger. Red stars are cooler that blue stars and so radiate less energy for a given amount of surface area. In order to radiate the same amount of energy as a blue star, the red star must therefore have a larger surface area.
What objects can radiate energy?
All objects radiate energy at a rate depending on their temperature.
How long will the white dwarf survive?
That depends what you mean with "survive". A white dwarf can be considered dead, it no longer produces energy. But it will continue emitting light for trillions of years; it has a lot of stored energy, and a small surface area to radiate it.That depends what you mean with "survive".

What is a absorber?
A heterotrophic absorber is an organism that gets its energy by consuming other organisms.
What is emission?

How energy transform in to wave?
All energy on gaining a high frequency become electro- magnetic radiation waves to radiate from the surface of the conductor through which electrons flow in the matter with additional energy input.
What is the meaning of pulsar?
radiate energy
