Why does black absorb colours that are are close to it in the spectrum?

Black absorbs all colors because the absense of all colors makes black. If all colors are absorbed, then no color is returned to your eyes and you see nothing (black).

What type of colours reflect all of the colors of light?
White reflects all the colours/wavelengths of light. Oppositely black would absorb all light. Hence you don't see light from a black object, you recognize the contrast between it and its surroundings. Any colours would be a mixture of absorption and reflection. If an object is transparent it reflects no(or close to as little as possible) light. Just an explanation based on science classes. -Jess
Color to wear to stay cool temperature?
White. Dark colours absorb heat, light colours reflect the heat.
What is the scientific explanation when a body is seen black?
If something appears black, that means it is absorbing strongly all of the different colours of the visible spectrum. Each of the colours correspond to a different energy of light and it is this energy that gets absorbed by electrons hopping up to higher electronic states in the material. When something is black, that means the energy levels in the valence and the conduction band are many and close together. This could be a a semiconductor with a very small band gap or a conductor (which technically doesn't have a separate valence or conduction band- just one big fat band partially full of electrons). Since there are many levels close together, electrons in the valence band can be excited to any number of many electron levels in the conduction band. Therefore these excitations can be of lots of different possible energies. This way the material can absorb all of the different energies of the different colours of visible light. Of course the material may actually be a mixture of materials that each absorb a different colour. The overall effect is a black appearance.
List of Shades of the color Black?
Black is a shade, but here are some dark colours close to it: Onyx Jet Sable Obsidian .
What are non-spectral colours?
the colors of the spectrum are: red, orange, yellow, green, blue, and violet. indigo used to be one of them till people decided to take it out cuz it was too close to violet.
What is the material that absorbs most incident light?
The visible light spectrum corresponds to the range of wavelength from0.38 to 0.76 microns of the electromagnetic radiation spectrum.Solid materials that have an absorptivity, α, close to 1 (a material withα = 1 is called a black body, and absorbs all the thermal radiation thathits him including visible light, a hypothetical concept) absorb most of theincident light radiation. Materials that have a mat (lusterless) black colorhave α close to 1.
Why might scientists mainly astronomers study the color of metals in a flame?
The colours with which an element (metal or other) burns in a flame are the same colours which are absorbed by that element in the sun's spectrum. The colours are very specific to each element and show up as distinct black lines in the solar spectrum. By studying the spectrum it is possible to tell what elements are in the sun [or star] and also their relative abundance.If a star is moving away from us absorption lines are red-shifted [move towards the red end of the spectrum]. The faster the star is moving away, the greater the red-shift. Also, as Hubble discovered, the greater the red-shift, the further away the star is. So the red shift in the absorption spectrum is a measure of not only how fast the star is receding from us but also how far it is. This allows us to tell whether two stars which are apparently in the same direction are actually close together or simply a coincidental alignment of their lines of sight.
What is result if you mixe together all the colors?
In paint, black. In light, white. In practice, if you mix all paint colours, you get a murky dark brown close to black. But the theory outlined above is correct.
Sentence for black hole?
A black hole is a type of star with excessive gravity. Here are some sentences.The star was sucked into the black hole close by.A black hole will even absorb light.The scientist is studying a black hole.
Why when you draw on black trousers with black pen it goes purple?
Because it's not actually black, it IS purple, unless its a felt tip, then it's green. It's due to the fact we cant make pure black so we use colours that are very very close. hope it helps
Where is the US mixed economy on the economic spectrum?
in the middle, but close to the capitalism.
How does a plant and animal cell look?
Plant and animal cells are usually round shaped with arms. It is impossible to see the colours because the microscopes that can go close enough are black and white.
