Festures of LED Fluorescent:

Fluorescent powder or Phosphors are often transition metal compounds or rare earth compounds of various types. The most common uses of phosphors are in CRT(cathode ray tube) displays and fluorescent lights. CRT phosphors were standardized beginning around World War II and designated by the letter "P" followed by a number.Phosphorus, the chemical element named for its light-emitting behavior, emits light due tochemiluminescence, not phosphorescence.

Q:Physics: Compare and contrast pigment color with the color seen from a light.?
you notice pigments the colour you notice them, using fact they replicate a spectra of sunshine, with particular frequencies, and take up all others seen to the human eye. in case you combine distinctive monochromatic mild with distinctive colours (as seen on the television: purple, green and blue it quite is referred to as additive mixing, or magenta, yellow and cyanide that's the different technique) your retina will upload the colors up, and experience it as a distinctive shade. (by skill of including each and all of the three colours on an identical intensity, you are able to create white mild) while mixing pigments (they are chemical compounds) you get a clean cloth, which will replicate an different spectra of sunshine, which you will see as a shade
Q:A pigment is a molecule that:?
B. It absorbs light.
Q:MAC pigments Vs MAC eyeshadow???
pigments are loose powder i believe. i like the eyeshadows better. there's a much better selection of those anyway.
Q:What colors do these pigments reflect?
Carotenoids generally reflect yellow, orange, or red and absorb blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm Beta-carotene absorbs most strongly between 400-500 nm. Fucoxanthin absorbs light primarily in the blue-green to yellow-green that penetrates deeper in water, peaking at around 510-525 nm and again at 450-540 nm. This reflects a yellow brown giving brown algae their color. Phycobilins are not found in leaves except as a phytochrome. They occur in Cyanobacteria (bluegreen algae) and Rhodophyta's (red algae) photosynthetic pathways as accessory pigments a part of the light reaction pigment systems energy donors to the reaction center. Phytochromes respond to far red between 700-800 nm. Phycoerythrin is a phycobilin pigment in rad algae that reflects red light and is therefore responsible for the color of most red algae.
Q:Is gel food coloring a pigment or a dye?
Dyes contain pigments, my friend. What is a pigment? They are like little beads. Very very tiny beads of the same color. Then if you spread these out, they give the thing a color. For example, the little green beads in leaves give it a green color. Pigment in our hair gives it a blonde/auburn/brown/black color. What is a dye? A dye is a liquid made up of water and pigments. The pigments are dissolved in water (well not really dissolve just that you cant see the beads) so that it's easier for us to use it. Everything that has a color is made up of pigments. So, gel food coloring is a thicker version of a dye that contains pigments.
Q:What exactly are pigments?
its a loose eyeshadow. you can press pigments and make them like eyeshadows [using 91% alcohol and pressing them.. look up youtube] pigments are loose powders that can be used just as they are.. or used foil which means you use them wet.. adding water or MAC fix plus on the brush or lid of the pigment. make sure not to spray the water in the whole pigment tho lol so they are pretty much just loose eyeshadows/powders
Q:Can someone describe the role of accessory pigments in photosynthesis?
Accessory Pigments In Plants
Q:what roles do pigments have in energy transfer?
Pigments okorder.com/... When a photon of just the right amount of energy strikes an electron resonating in the pigment, the electron can absorb the photon and get promoted to a higher quantum level. The photon must have just the exact amount of energy to boost the electron from its current level to its new level or it cannot be absorbed. If the incoming photon is just right to promote an electron, in that pigment, the newly energized electron resonates along the bonds at the higher energy level where it can pass to the photosynthetic reaction center from the pigment array, to split water and take back an electron. Meanwhile the chlorophyll's electron passes to the electron transport chain to begin oxidative phophorylation.
Q:How do you use pigments?
technically, pigment is a coloured mineral of a few type it relatively is floor as fantastic as available. (i.e., cobalt is blue, iron produces reds, etc.) Pigment is a similar whether it fairly is in cosmetics, ceramics, or in paint. in spite of the undeniable fact that, cutting-ingredient chemical ingredients can even have the end results of coloring the ingredients of cosmetics, yet that would lead them to a colorant, no longer a pigment.
Q:how are pigments classified?
Usually by what color they produce, i.e. all red pigments are classified together.
