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 pigments are used in photosynthesis?
- Chlorophyll(green) is the primary pigment used in photosynthesis. Besides chlorophyll, plants also use pigments such as carotenes(orange) and xanthophylls(yellow).
- Q: Please help me answer these Genetics problems. These are the problems that was assigned in the previous exams, but the professor doesn't provide the answer keys or a review session to go over these.Pigment in the mouse is produced only when the C allele is present. Individuals of the cc genotype have no color. if color is present, it may be determined by the A, a alleles. AA or Aa results in the agouti color, while aa results in the black color. In 3 crosses between agouti females whose genotypes are unknowns and males of the aacc genotype, the following phenotypic ratios were obtained. Female 1: 8 agouti 8 colorlessFemale 2: 4 agouti 5 black 10 colorless
- interior the 1st bypass AACC x aacc, discern a million will produce all AC gametes and discern 2 ac. Your F1 will all be AaCc. As all have the C allele they are going to be pigmented and as they're Aa they're going to all be agouti. Your F1 bypass is AaCc x AaCc. each and each discern can produce 4 gametes AC, Ac, aC, ac. To get all the genotypes you would be able to desire to entice a 4 x 4 Punnett sq.. each and each column and each and each row has between the 4 gametes in it and the cells comprise the blended genotypes. in case you count type up your genotypes you will discover 9 comprise the two A and C, those are agouti, 4 comprise cc, and all of those would be white regardless of the genotype at A, 3 comprise aa and C, those will all be black. So your phenotypic ratio would be 9:4:3 agouti: white: black the subsequent 3 crosses are all attempt crosses - you employ a recessive discern to artwork out the genotype of the different discern. a million. As lots of the offspring are colourless, you be attentive to that the two mothers and dads carry the c allele, as you pick cc for colourless mice. As there are no black mice, there is not any a allele interior the mum, as no aa offspring are produced. The bypass is AACc x aacc. woman gametes are AC or Ac and male gametes are all ac, offspring are the two AaCc or Aacc. 2. Is the opposite of bypass a million. There are black offspring so mom would desire to hold an a allele to furnish black mice, as there are no colourless ones, there is not any c allele interior the mum. you could write down the bypass and the F2 effect now. 3. This time all hues are produced, so the mum would desire to hold the two a and c alleles. Her genotype is AaCc, she would be able to offer 4 gametes as interior the 1st bypass and you will artwork out the resultant genotypes and phenotypes interior the F2.
- Q: How are plant pigments like teammates on a sports team? And What is the goal of their teamwork??
- WELL to be exact cuvette 2: to observe the role of photosynthesis with chromatin cuvette 3: to observe the role of photosynthesis with UV rays cuvette 4: to observe the stability of the chloroplasts cuvette 5: to observe the reaction of the H2O synthesis
- Q: 1.what is pigment2.what is it for ( whats its purpose?)3.what are other things people do with it
- Pigment is a loose powder that has highly concentrated color. They come in different finishes like matte or shimmery. You can use them as eye shadows and such, which is what most people do with them. They show up better and the metallic ones can be foiled (more vivid color and looks like metal almost) if you use them wet by putting a little bit of mixing medium or eye drops on your brush before dipping it in the pigment and applying it. They can also be used as lip colors by mixing with a clear lipgloss, or eyeliner if you use them wet or mix them with something like MAC's special eyeliner mixing medium. They also make a mascara mixing medium that can be used with pigments. Pigments really are a handy, universal product to have! Keep in mind that some pigments are not safe for use in the eye and/or lip area. If you look at MAC's website where the pigments are, you can check out the specifics about that under View Recommended Use. Also, if you use pigments wet, it's best to get a little bit of it in the jar lid, then dip the brush in it. That way you won't dampen and ruin the pigments in the jar, and moisture in the jar could promote the growth of bacteria.
- Q: Can someone describe the role of accessory pigments in photosynthesis?
- Accessory pigments help the plant absorb energy from different wavelengths of light other than those that are absorbed by the main pigment chlorophyl.
- Q: Pleaseeeeee answer A.S.A.P Pleaseeee! Are pigments haram?
- Most pigments for dyes and paints come from plants or minerals. What exactly do you need? The second part of your question about haram, needs some explanation, too.
- Q: (After the fifteenth century)
- Pigment is color in powder form. An example is lamp black; it was first made from the soot of kerosene lamps ground fine. Binder is a substance used to hold pigment together and make it adhere; in the previous example, linseed oil would be the binder for the lamp black pigment. Vehicle is a medium acting as a solvent, carrier, or binder for paint; turpentine or mineral spirits would be a vehicle but so would linseed oil as well to help dilute the paint and help it cover a large area. Hope that helps and thanx.
- Q: how exactly do pigments work? i know that they absorb every color except the one that we see, but what are the exact physics or whatever behind the selective absorption of the light?
- Photons are the packets of energy that light delivers. Different colors of light have different amounts of energy in each of the light's photons. So, green light's photons have different amounts of energy from red light's photons. Different materials absorb different amounts of energy via photons very selectively. It has to do with the energy states of the molecules, and the electrons that are in the outer shell.
- Q: HW HELP THIS IS COMLPCATED
- They're right. Chlorophyll is the Only pigment in plant cells.
