What is a perfect absorber or emitter of radiation called?
A perfect absorber or emitter of radiation is called a blackbody. It absorbs all incident radiation regardless of wavelength or direction, and emits radiation at the maximum possible level for a given temperature.
What radiation is released from plutonium 238?
Plutonium-238 is an alpha emitter.
What two factors of the electromagnetic radiation have an inverse relationship?
The intensity of any electromagnetic radiation is inversely proportional to the square of the distance of the emitter of that radiation.
What type of radiation is emitted by thorium?
Thorium-232 is an alpha emitter; rarely decay by spontaneous fission or double beta decay are possible.
What is it being When 100 percent of radiation bounces off of an object?
The radiation is being totally reflected.The object is absorbing momentum from the radiation, and is experiencinga force ... being 'pushed' ... in the direction that the radiation was travelingbefore the bounce.I'm not making that up.
What type of radiator of energy is an object that is a good absorber of radiation?
An object that is a good absorber of radiation is classified as a good emitter of radiation. It is known as a black body radiator, which absorbs and emits radiation efficiently across a wide range of wavelengths.
Is a good absorber of radiation a good emitter or a poor emitter?
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.
Is a good reflector of radiation a good emitter of radiation?
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.
Why does a black colour absorb more heat?
because its a good emitter/absorber of radiation
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?
A perfect absorber or emitter of radiation is called a blackbody. It absorbs all incident radiation regardless of wavelength or direction, and emits radiation at the maximum possible level for a given temperature.
What is the radiation of polonium 210?
Polonium-210 is an alpha emitter.
Is a good emitter of heat also a good reflector of heat?
Not necessarily. An object can be a good emitter of heat without being a good reflector of heat. The ability to emit and reflect heat depends on different properties of the material, such as surface texture and composition.
What radiation is released from plutonium 238?
Plutonium-238 is an alpha emitter.
What two factors of the electromagnetic radiation have an inverse relationship?
The intensity of any electromagnetic radiation is inversely proportional to the square of the distance of the emitter of that radiation.
If a poor absorber of radiation were a good emitter its temperature could remain?
constant. Because it emits radiation well, it would lose heat efficiently and balance with the heat gained from absorbing radiation, resulting in a stable temperature.
What is a perfect black body?
A perfect blackbody absorbs all radiation incident on it and It emits electromagnetic radiation in the form of thermal radiation from its surface. OR A perfect blackbody is a perfect emitter and perfect absorber.
