A good absorber of radiation is a good emitter. Radiation is the energy that that comes from a source and travels through space or through something. Some examples of radiation include light, heat and sound.

∙ 11y agonope, good absorbers are good emittors.
Think about it, if heat is reflected away from a reflector, how can it possess any heat to emit?

Is a good emitter of heat also a good reflector of heat?
Yes..
Is a good absorber of radiation a good emitter or a poor emitter?
It is a good emitter, as you can not have a good absorber, which isn't a good emitter. Dark, Matt surfaces are good emitters and absorbers e.g. a saucepan.
If a poor absorber of radiation were a good emitter its temperature could remain?
less than its surroundings
What is the difference between light producer and light reflector?
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
Can an object be both a good absorber and good reflector at the same time why or why not?
No, you can be both good and evil. This is the same concept. The object is either a good absorber or a good reflector, and can not be both. Black is a good absorber, white is a good reflector.
An object is a good emitter of radiation if it is what?
An object is a good emitter of radiation if it is a good absorber of radiation.
Is a good emitter of heat also a good reflector of heat?
Yes..

Why does a black colour absorb more heat?
because its a good emitter/absorber of radiation
If a poor absorber of radiation were a good emitter its temperature could remain?
less than its surroundings
between white and silver surfaces, which one is the best emitter of radiation?
The best emitter of radiation depends on the type of radiation you are referring to. Generally, when discussing thermal radiation, a "blackbody" is considered the best emitter. A blackbody is an idealized object that absorbs all incident radiation and emits radiation perfectly according to its temperature. In real-world scenarios, there is a concept called "emissivity," which quantifies how effectively an object emits thermal radiation compared to a blackbody at the same temperature. The emissivity of an object ranges between 0 and 1, with 1 being a perfect blackbody. Regarding white and silver surfaces: White surfaces: White surfaces tend to have high reflectivity and low emissivity. This means they are good at reflecting incoming radiation and do not emit thermal radiation as effectively. In terms of thermal radiation emission, they are not the best emitters. Silver surfaces: Silver surfaces also have high reflectivity but generally have higher emissivity compared to white surfaces. They emit more thermal radiation than white surfaces, but they are still not as effective emitters as a perfect blackbody. In conclusion, between white and silver surfaces, silver surfaces would be the better emitter of thermal radiation due to their higher emissivity. However, neither of them is as efficient as a blackbody emitter. Keep in mind that the exact emissivity values can vary based on the specific properties and conditions of the materials used.
What is a perfect absorber or emitter of radiation called?
Blackbody
What surface is the best reflector of radiation?
Light, shiny surfaces are the best reflectors of radiation
What is the radiation of polonium 210?
Polonium-210 is an alpha emitter.
What is the source of radioactive tracers in pipes?
a gamma radiation emitter
What is the difference between light producer and light reflector?
Source light is light coming directly from a light source/emitter (i.e. a light bulb, the sun, stars, etc.). Reflected light is light coming indirectly from the light source/emitter. That could be reflected, refracted light, etc.
What radiation is released from plutonium 238?
Plutonium-238 is an alpha emitter.
