- Q: (Explain what happens when a pigment molecule is struck by electromagnetic radiation in the visible light spectrum.)
- pigments are molecules that absorb electromagnetic radiation. For example, the chlorophyll pigment in plants absorbs blue and red light, which is why they reflect green light (since green is the color not absorbed). Another example is melanin, which is the pigment that darkens the skin of people. Melanin absorbs UV to protect the skin. A pigment molecule struck by EM radiation in the visible region may absorb some of the light depending on what pigment it is.
- Q: I am about to purchase a bunch of MAC pigments and I have noticed that they all look glittery, is this just the kind that i am looking at? I know they are versatile, so that is why i want to buy them. And it seems as though they will last longert than eyeshadow...
- they will last A LOT longer then eye shadows. and if you dont want the pigment to be as shiny i would suggest to mix it with an eyeshadow. i have also noticed they r all very glittery. sorry if this didnt help much Good luck! :)
- Q: How to manufacture FRP pigments?
- Pigment A finely divided material which contributes to optical and other properties of paint, finishes, and coatings. Pigments are insoluble in the coating material, whereas dyes dissolve in and color the coating. Pigments are mechanically mixed with the coating and are deposited when the coating dries. Their physical properties generally are not changed by incorporation in and deposition from the vehicle. Pigments may be classified according to composition (inorganic or organic) or by source (natural or synthetic). However, the most useful classification is by color (white, transparent, or colored) and by function. Special pigments include anticorrosive, metallic, and luminous pigments. See also Dye; Luminous paint; Paint.
- Q: PLEASE TRY!, to awnser ANY of the questions below.~What factors cause leaves to change colors. Where do these colors come from?~What are the names of the specific chemical pigments that cause the colors we see (reds, yellows, purples, browns, greens etc.) These are the same pigments (chemical that causes color) that give fruit their different colors.~What is the process (how it happens) that cause leaves to fall off of the branches. Explain at the cell level. (picture)Please try to awnser. Thanks.
- 1. Changes in pigment compsition is the primary reason for the changes in the colour observed during different developmental stages of leaves. 2. Each pigment has the property of absorbing light rays of certain wave lengths and reflecting rays of certain wave length. This is called chromatic property of the pigment. For example Chlorophyll absorbs all wavelengths and reflects green wave lengths. Hence it appears green in colour. Therefore the colour is in the light rays and not in the pigment. 3.Reds= Phycoerythrin; Yellows= Xanthophylls; Purples= Anthocyanins; Browns= different combinations of red and yellow pigments; greens= Chlorophylls; Blue= Phycocyanins. 4. Yes 5. The process of leaf fall is called Abcission. Leaf os an organ of definitive growth. It grows to its maximum size and becomes scenescent. Once scenescence sts in, all cellular materials that can be used elsewhere are translocated to other growing parts and the leaf becomes yellow. The water supply to the leaf is cut off. The phloem also becomes non-functional. At this stage a special layer called Abcission layer is formed at the base of leaf near the point of atachment to the stem. The abcission layer produces cork cells which plug the region. The layers of cells above the cork layer become deprived of water and food and die forming Separation layer. At this stage the leaf is attached to the base only by the xykem cells. By its shere weight the leaf breaks and falls. The most important point about abcission is that the exposed part of the leaf base is covered by cork layer which is impervious to entry of pathogens! Refer to any Plant Anatomy book for a diagram to show the longitudinal section of the abcission layer.
- Q: what pigment are? give two example
- pigments found in plants, vegetables and fruits, make them look colorful. pigments found in animal skins, givie us colorful animal skins with variety of shades. Plant pigment Chlorophyll makes plant leaves look green. Plant pigment Carotenoid makes fruits and vegetables look orange, yellow, red. Plant pigment Phycobilin makes plants look bluish green or red.
- Q: whats it for? lol
- itz for ur beautifing ur skin.
- Q: How do you use pigments?
- you can use it in a few places such as your lips, cheeks, eyes
- Q: i was thinking of this all day long and then i thought of posting this question for you to help me sort it out
- Pigments are molecules that absorb specific wavelengths (energies) of light and reflect all others. Pigments are colored: the color we see is the net effect of all the light reflecting back at us. Absorb: Electrons in molecules can exist at specific energy levels. Normally they exist at the lowest possible energy level they can. However, if enough energy comes along to boost them into the next level, they can absorb that energy and occupy that higher level. This is what pigments do. The light they absorb contains' just the right amount' of energy necessary to push them into the next level. Any light that does not have enough or has too much energy can not be absorbed and is reflected. The electron in the higher energy level, however, does not 'want' to stay there(i.e. it is unstable). It 'wants' to return to its normal lower energy level. In order to do this it must get rid or release the energy that has put it into the higher energy state to begin with. This can happen several different ways: 1) The extra energy can be converted into molecular motion and lost as heat. 2) Some of the extra energy can be lost as heat energy, while the rest is lost as light. This re-emission of light energy is called florescence. 3)The energy, but not the e- itself, can be passed onto another molecule. This is called resonance. 4)The energy and the e- can be transferred to another molecule. Plant pigments usually utilize the last two of these reactions to convert the sun's energy into their own. When chlorophyll is isolated from the enzymes it is associated with, the second scenario can be seen to happen.
- Q: how to prepare coloured pigments?
- Pigment does not might desire to do with pores and skin inevitably, a paint could be tinted with a pigment. curiously it is likewise a dry colorant, many times an insoluble powder. pores and skin colour is set by using the quantity of melanin in one's pores and skin, relative to ranges of exposure to the sunlight.
- 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.
