Excessive exposure to ultra violet light can lead to sun burn, skin cancer, and depending on the wave length of the light, cataracts. These conditions are not generally considered to be good for you.
The glow seen under ultraviolet light is called fluorescence. This phenomenon occurs when certain substances absorb ultraviolet light and then emit visible light in response.
Some minerals that glow under ultraviolet light are scheelite, amber, halite.
when it glows under ultraviolet light.
flourite
Calcite is a nonsilicate mineral that can exhibit fluorescence under ultraviolet light. It typically appears red, pink, or orange when exposed to UV light.
Yes, urine does not reflect ultraviolet light. Instead, it usually absorbs the ultraviolet light and might fluoresce under certain conditions.
The bad economic effects of sunbathing are:If you are laying out in the sun you are probably not working and making income, andIf you have enough unprotected exposure to ultraviolet from the sun, you may develop skin cancer and have to pay some or all of the costs of dealing with that.
one is cancer
I'd think that doing anything involving crystal meth would be bad.
Fluorite: Fluorite can exhibit a fluorescent response under ultraviolet light, emitting various colors. Calcite: Certain varieties of calcite, such as Iceland spar, can fluoresce under UV light, appearing red, blue, or green. Willemite: Willemite can fluoresce a bright green color under ultraviolet light due to traces of manganese.
FLOURESCENCE
Three minerals that glow under ultraviolet light are fluorite, calcite, and willemite. These minerals exhibit fluorescence, which is the emission of visible light after absorbing ultraviolet radiation.
