Fluorescent light is what astronomers call a "bright line" spectrum: there are only specific frequencies that are present, as opposed to the continuous rainbow one sees from a black body source (an incandescent light is basically a black body source).
You can get some idea by holding up a CD in fluorescent light so the light reflects off it and back to your eye, then moving it around a bit. Depending on the type of fluorescent bulb, you'll probably see anywhere from 3 to 5 distinct images of the source, each a different color.

What are some similarities between opaque transparent and translucent?
Opaque and transparent materials differ between the amount of light that passes through it. Opaque materials do not allow any light to pass through. Transparent materials allow all or most light through.
What makes diamonds give off different colours?
When white light passes through a prism it breaks into its coloured components(Red,Orange,Yellow,Green,Blue,Indigo and Violet).This process of breaking is known as dispersion. As the diamond is the crystal,when white light passes through,it acts like a prism. Therefore,white light breaks into its components,and we different types of colour
What is the Electrical power for a lightbulb?
The power rating for a light bulb (like "40 W") tells how much electrical power the light bulb uses. All of the power used by the bulb is either converted into light or heat. In an incandescent bulb, most of the energy becomes heat. In a fluorescent bulb, more of it becomes light.
How long does it take a star's light that is 7 light years away from Earth to reach Earth?
It's exactly 7 light years away.One light year is the distance that light travels through space in one year.7 of those is a distance of something like 41,150,289,900,000 miles.
Why does bread grow fastest in the light?
because yeast like light to grow
What are CFLs and LEDs?
A compact fluorescent light (CFL) is a fluorescent light that is manufactured in the approximate size and shape of a standard incandescent lamp. It's got an electronic ballast (unlike the standard fluorescent lamp tube which uses a heavy wire wound ballast), and it screws into a socket and performs on the standard line voltage like that aforementioned incandescent lamp. The light emitting diode (LED) is a solid state device that converts electricity into light without heating a filament like the incandescent lamp, or ionizing a gas like the fluorescent light does.

Is it possible to manufacture fluorescent ink?
Yes, fluorescent inks can be manufactured. And they are. To keep it simple, something that is fluorescent will fluoresce under high energy light, usually ultraviolet light. This high energy light will be absorbed by the fluorphore, and it will re-emit light of a lower energy, usually in the visible spectrum where we can see it. (The rest of the light energy of the incoming light will retained as heat - atomic and/or molecular vibration.) Fluorescent markers find application in the security or property control area where they are used to mark things like chairs or tables or stuff like that. The marks are invisible under normal circumstances, but will fluoresce and become visible under black light. Certainly there are still posters that are printed with fluorescent ink and look cool under black light.
Why does sunlight show up as a rainbow of colors in a spectroscope?
Because sunlight is made up of different wavelengths of light, it appears as a rainbow of colors in a spectroscope. Light is divided into its constituent wavelengths, which are perceived by humans as distinct colors, when it travels through a prism or diffraction grating in a spectroscope. The electromagnetic radiation spectrum that makes up sunlight ranges in wavelength from shorter ones like ultraviolet and violet to longer ones like red and infrared. A spectrum is a continuous band of colors that is created when the colors in sunlight are separated using a prism or diffraction grating. A particular wavelength of light is associated with each color in the spectrum. This dispersion happens when light waves go through a prism and bend or refract to differing degrees, spreading out and producing the rainbow-like pattern visible in a spectroscope. The visible spectrum is made up of a variety of colors, as this phenomenon shows, and sunshine is not just white light.
Should a new Curvalume T12 Fluorescent light rattle?
No, sounds like a piece of burned out filament moving around. Does it light up?
What are Fluorescent objects?
A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. I also put in the URL where I found the answer in case you would like to find out more about fluorescent lights.http://en.wikipedia.org/wiki/Fluorescent_lights
What is a sentence using the word fluorescent?
She did not like to look at herself in flourescent light, as she felt the natural sunshine was much kinder to her looks.

Can a dimmer switch be added on any light?
only regular lights like in ur house if u want to dimm a fluorescent light u have to change out the ballast to a dimmable ballast
Why do fluorescent tubes glow red at both ends only?
It has something to do with the energy waves that are moving through the bulb like a current.
How do CFLs work?
A compact fluorescent lamp rather than producing light by creating heat (i.e. like an incandescent light source), produces light by exciting mercury vapor inside the bulb's glass envelope. The initial excitation of gas is not enough to produce visible light (at this point it is actually UV light), the light produced is only visible once it passes through the phosphor coating on the inside of the bulb.
How many light bulbs were in the world trade centers?
It's pretty hard to know but there may have been over a million lights (like fluorescent light bulbs) in the WTC.
