What makes blacklight posters glow?
Who doesn't love black light posters? They were popular in the 1970's though they can still be found today. They glow because of the ink used to print them. When the posters are exposed to ultraviolet light that comes from the black lights, it produces a fluorescent glow.
How does fluorescent work?
Fluorescent lights glow because of an electric discharge in a glass tube that causes mercury atoms to emit ultraviolet light. The inside of the tube is coated with phosphor, which absorbs the ultraviolet light and then re-emits visible light.
Is fluorescent light produced by heat?
Not in the way that an incandescent bulb does. A fluorescent lamp uses electricity to excite the particles of mercury vapor in the tube. This excited gas causes a phosphor to glow.
How is fluorescent different from natural light?
Well.. the difference is that fluorescent light isn't natural and natural light isn't fluorescent . its not rocket science (:
Why do fluorescent light glow when turned off?
Fluorescent lights use electric current to excite mercury atoms, which emit UV light. The tube part of the light is covered in phosphorescent material, which is excited by the UV light the mercury produces, and emits visible light. The reason they glow is because it takes a while for an excited mercury atom to emit the UV light, and it takes even longer for the excited phosphorescent molecules to emit all of their excess energy and return to their normal energy levels, also called the ground state. The path of the energy is Electricity -> UV light-> Visible light-> your eye
Do fluorescent markers glow under a black light?
Yes of course, that is why they are fluorescent.
What happens to fluorescent minerals when light shines on them?

What makes a color fluorescent?
Fluorescent colors contain pigments or dyes that can absorb and emit light at specific wavelengths. They often contain fluorescent dyes that are able to absorb ultraviolet light and then re-emit it as visible light, resulting in the vibrant and intense colors that we perceive as fluorescent. The absorption and emission properties of these dyes are what give fluorescent colors their characteristic brightness and glow.
Do diamonds glow in fluorescent light?
Yes, they have a tenancy to emit a soft colored glow when subjected to ultraviolet light. Famously, the Hope Diamond will glow red-orange for about five minutes.
When is a mineral is discribed as fluorescent?
A mineral is described as a fluorescent when light from ultraviolet lamps reacts with the chemicals of a mineral and causes the mineral to glow; this is called fluorescence.
How are some corals fluorescent?
Do you mean, "Why does coral glow in ultraviolet light?", "Why does some coral glow in the dark?", or something else. Please be more specific.
Does fluorescent material glow under infrared light?
No fluorescent material glows under ultraviolet not infrared
Why does incandescent light not glow on material?
Incandescent light bulbs do not emit much Ultraviolet light. Strip lights and compact fluorescent low energy light bulbs do. The whiteners added to white fabrics react to UV light and glow due to fluorescence.
What makes bacteria glow green?
light
