what is description of light
Light does not have a color. An object absorbs light of all sorts of frequencies, but will re-emit some of these frequencies. Those that happen to be in the visible spectrum will ultimately be absorbed by the cones in our eyes. There are three types of cones, long, medium, and short and they correspond to a certain range of frequencies of light in which they 'specialize' in the absorption of. The peak absorptions for the three cones are perceived by our brains to be associated with the general colors red, blue, and green-- the primary colors. When the brain perceives data from light absorbed by all three cones, the brain begins to distinguish between the different shades and hues and refine the color. Your brain is using colors to distinguish between the various frequencies your cones absorb, the light itself doesn't have a color.
I bought a nail polish unknowing that i needed a UV or LED light. Will a fluorescent light do the same thing? Or a black light?
Most brands of nail polish that require UV needs the light to be at a wavelength of 365nm. Ordinary fluorescent lights don't work. An ordinary cheap black light should, as long as it's bright enough. The kind you need is known in the lighting industry as blacklight blue. Nail curing systems usually have four 9-watt tubes for a total of 36 watts. Because the bulbs are compact, the light is concentrated where it's needed. For this reason, you may have a hard time getting enough UV light concentrated on your nails. If you look online, you'll see that UV nail-curing systems are not that expensive (about $30). As for LEDs, they have them at 365nm, but they are expensive, starting at about $10 for one LED. Direct sunlight would probably do it.

I would like to find out what people think the best light beer might be. Thanks.
I drink a lot of Michelob Ultra, but the best beer I ever had was this stuff called Warsteiner that I drank when I was in Germany for 3 1/2 years. Warsteiner is a full flavored beer with a kick, but went down smooth.
Do you usually prefer getting with your partner when the lights are on or off? Just curious. Why?Me: I prefer lights on, but I like candlelight when we're going for slow and intimate. It's just fun to see him and everything that's going on.
I like lights on, I have an adjustable light switch, but I like it bright enough so I can her eyes when we make love. If I'm at her house, she'll turn her lamp on. Sometimes though (this is the best) she'll wake me up early in the morning by rubbing me or kissing me, and lights stay off in that situation. 90% of the time, it's lights on in some way or another.
