Festures of LED Fluorescent:

Fluorescent powder, also called phosphor, most generally, is a substance that exhibits the phenomenon of luminescence. Somewhat confusingly, this includes both phosphorescent materials, which show a slow decay in brightness (> 1 ms), and fluorescent materials, where the emission decay takes place over tens of nanoseconds. Phosphorescent materials are known for their use in radar screens and glow-in-the-dark toys, whereas fluorescent materials are common in cathode ray tube (CRT) and plasma video display screens, sensors, and white LEDs.

Q:what are the three major photosythetic pigments?
three major pigments are 1.chlorophyll a 2.chlorophyll b 3.carotenoids chlorophyll a is the major pigment,chlorophyll b n carotenoid are the accessory pigments which help in absorption of the incident light of different wavelengths. another pigment xanthopyll-fucoxanthin is also present in some plants
Q:whats pigment?
It's a small plant that pigs love to eat. It's sort of like catnip, except that pigs love it (cats won't touch it). It is related to the catnip and mint family of plants.
Q:what is the function of pigment molecules in photosynthesis?
They absorb light from the sun
Q:Powdered paint/pigment question?
Smash up sidewalk chalk.
Q:what is the relationship between chlorophyll a, accessory pigment?
Chlorophyll is the pigment that allows plants—including algae—to convert sunlight into organic compounds in the process of photosynthesis. Chlorophyll a is the predominant type found in algae and cyanobacteria (blue-green algae), and its abundance is a good indicator of the amount of algae present in the waters of the Chesapeake Bay. Excessive quantities of chlorophyll a can indicate the presence of algae blooms. These usually consist of a single species of algae, typically a species undesirable for fish and other predators to consume. Unconsumed algae sink to the bottom and decay, using up the oxygen required by other plants and benthic organisms to survive. The presence of too many nutrients, such as nitrogen and phosphorus, can stimulate algal blooms and result in reduced water clarity. Chlorophyll a also plays a direct role in reducing the amount of light avalable to plants in shallow-water habitats. This directly impacts the ability of underwater bay grasses to thrive. Like their terretrial cousins, grasses need sunlight to grow. As chlorophyll a levels increase, the amount of sunlight reaching underwater grasses declines. Chlorophyll a is the main pigment, chlorophyll b and carotenoids are accessory pigments. accessory pigments help broaden the absorbtion spectrum, as chlorophyll a absorbs violet-blue and red light. with the addition of accessory pigments chlorophyll b and carotenoids, yellow-green (chlor b) and violet and blue-green light (caro)
Q:How many pigments does grass reflect?
Pigments are the colors that make grass look green. They are the pigments that do photosynthesis. Grass looks green because it reflects green light. It reflects the wavelengths of light that have the frequency of green light. Grass has other pigments that we do not see through the chlorophyll, but it is the light that is reflected.
Q:How do you make paint pigments?
Pigments are specific minerals found in rocks. Then they are ground down and mixed with the binders for oil, acrylic, and watercolor paints. You can take art classes that teach you how to make your own paints. I have a cousin who hikes to find her own pigments and makes all the colors she paint with. If you'd like something less labor-intensive, you can buy the pigments you want from lots of art stores these days. They can be added to pre-existing colors to enhance them, or you can start from scratch to formulate your own colors. The bottles i've seen are around 8 ounces, and cost about $50. You will likely find books in the library and articles online that will help you learn to make your own pigments.
Q:what is the difference between light color and pigment colors?
Pigments are chemicals that selectively absorb and reflect different spectra of light. When a surface is painted with a pigment, light hitting the surface is reflected, minus some wavelengths. This subtraction of wavelengths produces the appearance of different colors. Most paints are a blend of several chemical pigments, intended to produce a reflection of a given color.
Q:what looks good with mac melon pigment?
With the Melon pigment, I would recommend using warm, chocolate copper, bronze types of colors. It will provide a nice contrast to the melon while giving your eyes some added depth and definition. As far as brushes go, I like using the 252, large shader brush. This brush picks up pigment nicely and it has nice compressed/dense bristles so you can manipulate and lay the pigment down with greater ease. I like the #286 The dual fiber blending brush for pigments as well. It's made of natural fiber and synthetic fiber. This is a great brush because you really get 2 brushes in 1. With this 'blending' brush you can also use it for targeted color deposits and the synthetic fibers won't suck up what you just laid down and you will get a flawless, beautifully blended eyeshadow application.
Q:complete the table below to organize your thoughts about plant pigments?
pigment: .... reflected color to eyes .. what color of light it absorbs Chl a reflects green spectra between the blue and red absorption peaks. Some is absorbed at blue 450nm but most absorbed at red 680 - 700nm. Chl b reflects green spectra between the blue and red absorption peaks with a difference in which peak is stronger. Most is absorbed at blue 470 but also some at blue 430 and red 640 nm. Cartenoids reflect yellow, orange, or red and absorbs blue to blue-green light spectra. Xanthophyll absorbs well at 400-530 nm. Xanthophylls are a common sub class of the carotenoid pigment group. Beta-carotene absorbs most strongly between 400-500 nm.
