Which portion of the electromagnetic spectrum is used to identify fluorescent minerals?
The UV portion of the spectrum
How is fluorescent different from natural light?
Well.. the difference is that fluorescent light isn't natural and natural light isn't fluorescent . its not rocket science (:
What are the energy transformations of a fluorescent light bulb?
When a fluorescent lamp is turned on, the electricity excites the mercury vapor inside the tube. UV light is produced. The UV light excites the phosphor coating. The phosphorus atoms relax by releasing a visible light. Since the light emitted by the phosphorus atoms is of a spread spectrum (the frequency is not fixed), the light appears whitish. To summarize, electricity is turned into light.
The light-producing element in a fluorescent bulb is the?
Light in fluorescent bulbs occurs when electricity excites the mercury vapor inside the tubular glass bulb.
What is a invisble light spectrum?
Most of the electromagnetic spectrum is not visible.
How is a light bulb better for growing plants then a fluorescent?
The light spectrum from an incandescent (a bulb) is closer to the spectrum of the sun than what comes from a fluorescent.
What is unique about the spectrum obtained for a fluorescent light?
Nothing. Chemistry is for fools.
Which of these would be a classic continuous spectrum a rainbow the sunlight a neon light fluorescent light or a glowing nebula?
The answer is Rainbow!...
What is a similarity in the line spectrum of mercury and the spectrum of the fluorescent bulb?
A fluorescent lamp contain mercury so the identities of spectrum are normal.
Will a condensed fluorescent bulb work as a grow light for garden?
Only if you buy a "full spectrum" of "grow light" type of compact bulb.
What is a example of phosphorescence?
its the souce of light offered from a tube light.... its white light, with all spectrum of colours
What is a growlight?
A Growlight is a special type of light bulb that is used in horticulture. it tries to mimic the light spectrum produced by the sun - as normal light bulbs (incandescent and fluorescent) do not provide the correct spectrum of light required for healthy plant growth
Which portion of the electromagnetic spectrum is used to identify fluorescent minerals?
The UV portion of the spectrum
Where will a full range of colors be better seen in a room with fluorescent or outside under daylight?
Daylight will have a more complete spectrum. An interesting experiment is to hold a CD close to a fluorescent lamp. The CD will act as a primitive diffraction grating, and you'll see distinct blobs of colour - not a continuous rainbow spectrum. You're seeing the light emitted by the various phosphors in the fluorescent tube.
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.
