Electromagnetic radiation causes certain substanced to fluoresce?
Yes. UV radiation causes phosphor to fluoresce in fluorescent light bulbs.
In what wavelength region does caffeine fluoresce?
When excited by 532 nm green light, caffeine has been seen to fluoresce in the 625 nm wavelength region. This is visible orange light.
What is the chemical compound in Lysol which causes it to fluoresce under a black light?
chemicals
Why are fabrics that fluoresce when exposed to ultraviolet light so bright in sunlight?
i have the same question ni99a
What color is carotene under a UV light?
Carotene will fluoresce in UV light, but the "colour" of the fluorescence is infra red and cannot been seen by the human eye.
What does uv light detect in a crime scene?
Ultraviolet (UV) light causes some body fluids, such as urine and semen, to fluoresce, making them visible to the naked eye.
When was Canadian Light Source created?
Canadian Light Source was created in 1999.
What is meant when they say florescents have been observed when drilling for oil?
Light waves shorter than the visible blue violet waves of the spectrum. crude oil, colored distillates, residuum, a few drilling fluid additives, and certain minerals and chemicals fluoresce in the presence of ultraviolet light. these substances, when present in mud, may cause the mud to fluoresce.
How is visible light generated?
The simple answer is heat. If you heat anything enough it will start generating light. <><><> In addition to the above, materials that fluoresce will give off visible light when stimulated by various energies. See fluorescent light, Light Emitting Diodes, etc
Which rocks glow in UV light?
scorpions doThe hyaline layer of a scorpion exoskeleton fluoresces under a UV light, turning teal green. Scientist don't yet understand the material causing it to fluoresce; but scorpion fossils that are millions of years old still fluoresce.Other animals that fluoresce include crayfish, centipedes, and millipedes.
What does fluorecent mean?
It generally means "glowing" - certain elements "fluoresce" (give off a visible light) when hit by electromagnetic radiation, even when the radiation itself is invisible (e.g. UV light). An example is in fluorescent lighting tubes where mercury vapor is electrified to cause a phosphor coating to fluoresce. A slower process called phosphorescence occurs where glow-in-the-dark stickers absorb light and radiate it back slowly as a greenish glow.
What kind of light is used to excite dyes and make microorganisms fluoresce?
Clone microorganism with Green Fluoresenct protein , culture it , Observe the cultures appears green
