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 changes Electrical Energy to light energy?
Electrical energy is converted to light energy through a process called electroluminescence, where the energy from electrons flowing through a material is released as light. This conversion occurs in devices like light bulbs, LEDs, and fluorescent lamps.
What is a sentence using the word fluorescent?
The fluorescent light bulb in the office was energy-efficient and emitted a bright blue light.
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.

What do colors look like viewed indoors under fluorescent light and outdoors in sunlight?
Colors may appear brighter and cooler under fluorescent light indoors, as fluorescent light emits a bluish light which can affect color perception. Outdoors in sunlight, colors appear more natural and vibrant, as sunlight provides a full spectrum of light that accurately represents colors.
How do you make fluorescent blue?
To make a fluorescent blue color, you can mix a bright blue pigment with a fluorescent additive like fluorescent blue paint or powder. This will give your blue color a vibrant glow under UV light. Experiment with different ratios to achieve the desired fluorescent effect.
What colors are absorbed by black light?
Black light emits ultraviolet (UV) light, so it typically excites fluorescent materials that absorb UV light and re-emit visible light. Fluorescent colors that appear bright under black light include neon colors like pink, green, orange, and yellow. Other colors without fluorescent properties may appear muted or black under black light.
Why does sunlight show up as a rainbow of colors in a spectroscope?
Sunlight is made up of a spectrum of colors because it contains various wavelengths of light. When sunlight passes through a spectroscope, the prism inside disperses the light, separating it into its different wavelengths. Each color corresponds to a specific wavelength, creating the beautiful rainbow spectrum we see.
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.
What are Fluorescent objects?
Fluorescent objects are materials that absorb ultraviolet (UV) or visible light and then re-emit light at a longer wavelength, typically in the visible spectrum. This phenomenon is called fluorescence, and it produces the characteristic bright and vibrant colors seen in fluorescent materials like highlighter markers and certain minerals.
How can I create a DIY spectroscope at home?
To create a DIY spectroscope at home, you will need a cardboard tube, a CD or DVD, a small piece of aluminum foil, a sharp knife or scissors, and tape. Start by cutting a small slit in the cardboard tube and covering it with the aluminum foil. Then, tape the CD or DVD to one end of the tube, making sure the foil-covered slit is aligned with the edge of the disc. Finally, shine a light through the other end of the tube and look through the CD to see the spectrum of light.
What are the key differences between a spectroscope and a spectrometer, and how do these differences impact their respective functions in analyzing light and measuring spectral data?
A spectroscope is a device used to observe and analyze the visible spectrum of light, while a spectrometer is a more advanced instrument that can measure and analyze the entire spectrum of light, including invisible wavelengths. The key difference is that a spectrometer provides more detailed and accurate data compared to a spectroscope. This difference allows spectrometers to be more precise in analyzing light and measuring spectral data for various scientific applications.
