:O It's so weird!
In the general sense fluorescence occurs because something absorbs light from part of the light spectrum we don't see and emits light we do.
Many things fluoresce. Fluorescent lamps work by producing invisible UV light that excites a phosphor coating inside the lamp that emits visible light. When UV strikes fluorescent chemicals an electron is excited to a higher energy state (orbit), when it falls back to its original energy state a photon or light is produced in the visual spectrum. A black light is typically a fluorescent lamp without the phosphor coating inside so it emits mostly UV instead of visible light. When this light hits fluorescent chemicals they do the same thing phosphor does and emit visible light.
Laundry products that promise "whiter than whites" or to make colors brighter contain fluorescent chemicals that convert UV to visible light; the extra light makes your clothes brighter. The "bluing" your grandmother used to make whites brighter did the same thing.
A lot of people don't realize it but tonic water is fluorescent. I usually order a tonic water drinks when I'm someplace with black lights.
yea girlie all pets urine glow up under a uv light the uv light helps people to clean pet's urine bc if u use like regular household materials to clean it without the uv light to see, u won't get all of the urnie up though it may look like you have gotten it all up u really haven't
i believe the uria (chemical in the pee) naturaly has a glow... it was one of the first compounds discovered because a guy ate some stuff and made his glow lol
Lol, black lights, and strobe lights are awesome for parties, or just to have in your bedroom for a cool effect! :)
lol...get a cat, wait until it pee's, and then observe the pee under a black light...you'll see! :D It glows! :D
Attractive question there ! haha it prob has something to do witht he chemicals in the pee.
