What happens a lot if one bulb breaks in you Christmas lights?
it depends on what kind of Christmas lights you have
What kind of UV light comes from a Highpressure sodium lamp?
The ultraviolet spectrum is the highest energy light at the end of the visible electromagnetic spectrum. We can see it by what it does. That does not mean that we can't see it. We can see the starting edge of it. Like all of the visible colors it is hard to determine when one bleeds into the next. It is actually harmful to look at it. It is what causes sunburns. The ultraviolet wavelength in Mercury's spectrum is around 4,000 angstroms or 400 nanometers.
A neon light is more similar to an incandescent light or a fluorescent light explain how you know?
A neon light is much more similar to a fluorescent light. I know because I have a Ph.D. in physical chemistry, but I suspect you mean "justify your answer," so here goes. In a gas-discharge light (a neon light), a gas is ionized by an electric potential. Free electrons are then accelerated through the ionized gas. This causes the ions to transition into an excited electronic state. When the ion decays back to the ground state, energy of characteristic frequencies is emitted; the dominant frequencies depend on the gas, the voltage, and the pressure. This is why neon lights are orange-red: the dominant characteristic visible frequencies for neon gas are in the orange-red portion of the spectrum. (If you see a "neon" light that isn't orange-red, it's probably not really using neon gas.) A fluorescent light is exactly the same, except that the inside of the tube is coated with a fluorescent material. It absorbs the (high frequency) energy emitted by the gas discharge itself, and emits energy at a lower frequency (characteristic of the specific material). The gas in fluorescent lights is usually low-pressure mercury vapor, whose dominant emisison frequencies are in the ultraviolet. This is absorbed by the phosphor in the tube and re-emitted as a lower frequency (in the visible spectrum). Most fluorescent lights have a mixture of phosphors so that the emitted light appears "white" because it's actually a mix of different colors that kind of "average out" to white (this is like how the red, green, and blue phosphors in a CRT "blend" to appear white). To confuse matters even further, a lot of modern "neon" lights are actually just fluorescent lights with a colored dye or sleeve applied to the tube (if the tube, when off, appears white, colored, or "cloudy", it's probably a fluorescent light instead; if it's clear and looks empty, then it's pure gas-discharge). This allows for the production of "neon" lights of any color desired and also allows different sections of the tube to have different colors. An incandescent light glows because it's hot ("black body" radiation or "cavity" radiation). There's no characteristic frequency, though there is an emissions maximum which varies depending on temperature. If it's relatively cool ("red hot" is relatively cool as used here), it will appear a dull red; as it gets hotter it turns bright red, then orange, then yellow, then white, and ultimately starts to appear to have a bluish tinge as the emissions maximum shifts to shorter and shorter wavelengths.
Which type of fossils is found only rarely?
Maybe a T rex or some other kind of dinosaur
How do you make light green?
paint a light bulb green, or alternatively, pop into B&Q and buy a green light bulb, eco friendly or filament, it's up to you, but i suggest eco friendly, get it? with the whole "green" situation
Which kind a light bulb uses the least amount of energy a fluorescent lamp a halogen lamp a incandescent lamp or a heating lamp?
Fluorescent lights use far less energy than any of the others listed.
Why does the sun produce a continuous spectrum but the fluorescent lights produce a line spectrum?
The sun produces a (nearly) continuous spectrum (gaseous elements in the Sun's atmosphere absorb certain frequencies, making it not quite truly continuous) because it's emitting light due mainly to its temperature. This kind of radiation is called "black body" or "cavity" radiation, and it's a continuous spectrum. Fluorescent lights produce light by a phenomenon known as (hold on for the shocking revelation) fluorescence. This kind of radiation is related to transitions between specific electron energy levels, and therefore consists of discrete lines. In old or cheap fluorescent tubes, there might be only a couple of lines. Most modern ones use a mixture of phosphors that emit light at different frequencies, so you might see half a dozen or more lines in the spectrum.
What kind of lights are in hospitals?
Very bright fluorescent lights!!
What kind of light bulbs should you use for plants?
Because the type and concentration of chlorophyll pigments in the plant can vary, an unfrosted incandescent bulb is the best choice as it emits light over the entire visible spectrum whereas fluorescent lights generally emit very specific wavelengths depending on the gasses they contain.
What kind of lights do you need to trick plant?
fluorescent
What is a lumen How does it relate to watts?
A lumen is a unit of luminous flux, which is the amount of light emitted per unit time. A watt is a unit of power (such as electrical power), which is the amount of energy consumed per unit time. Light bulbs have ratings in watts, which measures how much electricity they use, and lumens, which measures how much light they give off. For the same kind of bulb (incandescent, fluorescent, LED, etc.), a bulb with a higher wattage will produce more lumens. However, a 10-watt LED or compact fluorescent bulb may produce more lumens than a 40-watt incandescent bulb.
Why does the colors of an object look different under a fluorescent lamp from the way it looks under an incandescent lamp?
differences in the color of light will change the color's appearance as it is seen under fluorescent and incandescent. An incandescent lamp, like the sun, produces a spectrum of light in every color in a wide band, broad enough to cover the entire visible spectrum -- and extending past it to many colors that humans can't see. A fluorescent lamp produces a spectrum of light in a few narrower bands of color. That is why a fluorescent lamp is more energy efficient than a incandescent -- the fluorescent lamp doesn't waste energy producing photons that humans can't see. Some materials (such as white paper) reflect all visible colors equally. They look white in almost any kind of light. Other materials absorb some colors more strongly than other colors. They look colored in "white" incandescent light. If we have a material that reflects most colors equally, except for a narrow band of colors, and that band is in the "dark" part of of the fluorescent spectrum -- it will look the same color as white paper. If we have another material that reflects most colors equally, except for a narrow band of colors that is in one of the bands of colors produced by a flourescent lamp -- that material will look even more deeply colored in fluorescent light than in incandescent light.
What kind of energy does a fluorescent light produce?
Main one is light energy. Also some heat is produced
Which bulbs are best for daylight lamps?
When you're looking for a bulb for a daylight lamp, the best ones are going to be full spectrum light bulbs. They are pure white light and is a natural appearing daylight color. If you suffer from S.A.D., or winter blues, then this is the kind of light bulb that you would be looking for.

What does 'fluorescent urine' mean?
Fluorescent urine means.......well fluorescent means like glowing and urine means liquid or water. So I suggest it means glowing liquid or something. If you were using markers and if it said fluorescent urine it would mean that the markers are bright and they kind of glow.
Will Compact Fluorescent light bulbs interfere with garage door opener receivers?
AnswerThey shouldn't; that kind of thing is checked and regulated by the FCC. However, a CFL has a high frequency switching power supply in it, so it is possible. My garage door opener would not open or close until the the compact fluorescent light bulb timed out. There is a warning on the CFB that says that it can interfere with electronic circuits and it does.
