Why does an object appear to be black in color?
An object would appear black if:it did not emit any visible radiation.it was in an environment where there was no ambient visible radiation present.the compounds on its surface absorbed all radiation comprising the visible spectrum.
Does black hold heat?
When a molecule absorbs visible or ultraviolet radiation, electrons in their ground state are promoted to higher states. Through various types of decay, the electrons fall back to their ground states. During this process, some infrared radiation is emitted, which is felt as heat. Black materials emit more infrared radiation because most of the decay of electrons from excited states to ground states involves infrared radiation emission.
Is microwave radiation the same as infrared radiation?
Answer No.Infrared radiation is electromagnetic radiation at wavelengths between 750 nanometres and 1 millimetre.Thermal radiation is all electromagnetic radiation emitted from an object due to its temperature and follows a "black body spectrum".The reason we generally refer to Infrared as 'heat' is because that is the main form of radiation emitted from objects at temperatures we encounter day to day. In actual fact, ANY electromagnetic radiation can heat a surface it hits. So yes, you can be warmed by yellow light if it was bright enough.So to clarify, thermal radiation can sometimes be infrared (and sometimes yellow, or red, or blue, or ultraviolet, or microwave, or radio!). Infrared radiation can sometimes be thermal (but can be generated by methods other than an object's heat).The thermal radiation your body emits is mostly far infrared with some very weak microwaves.The thermal radiation from the Big Bang is 3K, so cold that it has no infrared at all in it, only microwave, UHF/VHF (causing snow on the older analog TV screens), and some very weak shortwave radio!The thermal radiation from a few very very big and hot Blue Giant stars is actually mostly x-rays!
What portion of the spectrum does suns black body curve peak?
It peaks in the visible spectrum.
What light includes all colors from the spectrum?
Any light that originated from heat consist of light at all spectrum band. I believe you might want to know if it is white light, from human biology we do see the overall light's colour as white even if the light compose from just red blue and green. Only light that come from source of heating like Sun light, candle, wood fire do contain the full spectrum. The thermal radiation is also called black body radiation.
What becomes of gamma radiation emitted by black holes?
Black holes do not emit anything.
At what temperature heat energy is converted to light energy?
Black-body radiation is the type of electromagnetic radiation within or surrounding a body in thermodynamic equilibrium with its environment, or emitted by a black body (an opaque and non-reflective body) held at constant, uniform temperature. The radiation has a specific spectrum and intensity that depends only on the temperature of the body.
What were some of Stephan Hawkin's contributions to astronomy?
For one, he came up with the Hawking radiation, which is emitted by black holes.
How does a quasar work?
A quasar is believed to have a supermassive black hole at its center. The radiation is emitted outside the black hole's event horizon - from matter that is falling into the black hole.
Does candle light have a continuous light spectrum?
Yes. Candle light is an example of black body radiation.
Why x ray or gamma ray are not emitted from blackbody spectrum?
For gamma rays, it's by definition. Gamma rays are emitted from nuclear decay events, so even if a black body were to emit a photon with the same frequency as a gamma ray, it wouldn't be a gamma ray.X-rays, though... at the high frequency end of the spectrum, the intensity of the radiation emitted is proportional to e-v. Since v (which should really be a Greek nu) for X-rays starts at around 3x1016, e-v is a very very small number indeed.
If you heat a piece of wire until it glow's what type of spectrum does it produce?
Well I know if you heat a rock until it glows, its spectrum will be thermal radaition spectrum
Is a black hloe a black body?
No. These two scientific terminologies have pretty much nothing in common beyond having the word "black" in them. Light emitted from a black hole is not, in any way, the same as black body radiation.
Why black paper wrapped around photo graphic plate during detection of nuclear radiation?
it absorbs almost all the emitted radiations
Why light emitted by bulb is not monochromatic?
Light bulbs aim to emulate the light emitted by the Sun, which radiates as a black body at 6000 degrees C. The light is emitted over the entire visible spectrum. Some bulbs produce monochromatic light, sodium street lights for example.
Why does an object appear to be black in color?
An object would appear black if:it did not emit any visible radiation.it was in an environment where there was no ambient visible radiation present.the compounds on its surface absorbed all radiation comprising the visible spectrum.
What is the colour of a black body?
The term "black body," as related to "black body radiation," is a hold-over from the study of such light during the 1800s. BBR is emitted from any object that has a temperature. Such an object can be of any color.
