How do planets glow?
They don't glow. They reflect the light from the sun.
What will cause magnesium to glow brighter?
Increasing the temperature of magnesium will cause it to glow brighter. Heating magnesium to a high temperature excites the electrons in the atoms, causing them to jump to higher energy levels. As the electrons return to their lower energy levels, they release energy in the form of light, resulting in a brighter glow.
IF a bulb travels at the speed of light and is turned on will it glow?
It could not travel at the speed of light. But hypothetically, it would glow.
Why do glow-in-the-dark things stop glowing after some time?
When things that are supposed to glow in the dark don't, it is usually because they were not exposed to other sources of light. For example, glow stars only glow if the light in the room they decorate has been on for sometime, in a kind of absorbtion process. Without previous contact with a light source they can't glow.
Why does iron become red during heating?
Is that really your question? Do you mean in the experiment when iron and sulfur are mixed and heated why does it glow red? During the experiment iron and sulfur begin to react at higher temperatures. As they react there is a release of energy, some of which is heat and some is in the red light region. During the reaction iron sulfide is produced. More simplistically, heating many things caused them to glow red. Heating iron can cause the iron alone to start giving off a red glow because while absorbing the heat the electrons in the atoms move to a higher energy level. Some of that absorbeb energy is released as the electrons move back to lower energy levels releasing some energy as red light waves.
What are the genes on the pVIB plasmid?
It contains a gene for luciferase, a Lux gene (the enzyme that catalyzes the light-emitting reaction) and genes for enzymes which produce the luciferins (which are the substrates for the light-emitting reaction.). This causes bacterial cells to glow!
How does a battery make a light bulb glow?
The flow of electrons from the battery flow through the filament in the bulb causing it to get hot and glow thus producing light.
What causes filament in a light bulb to glow?
Current passing through a special wire like tungsten heat up the wire and create light by emitting photons
Will a infrared led kept in sunlight glow or not?
There is no such thing as and an infra-red LED. Nor will an any LED glow without a power source. That power may come from a solar cell but an LED (Light Emitting Diode) emits light it does not collect light energy.
Why do things glow in the dark?
they absorb light from before and then when it is dark they glow the absorbed light
Is it possible to have a glow in the dark material that would charge up with re light then emit blue light as it glow?
yes. when a glow in the dark material "charges" photons are hitting it making the electrons move to a different energy shell. when that electron returns to its native level it releases radiation we see as light. what colour the light is dependent on the molecule the electron was a part of not the kind of light that hit it making it move up in the first place.
What type of light do glow sticks react to?
Glow sticks are a chemical light.
Substances which will glow in the dark after being exposed to sunlight are called?
phosphoresce phos·pho·resced, phos·pho·resc·ing, phos·pho·resc·es To persist in emitting light, unaccompanied by sensible heat or combustion, after exposure to and removal of a source of radiation.
Phosphorus atoms embedded in plastic absorb light energy and slowly release the light in a glow-in- the dark process is called?
In some elements it takes time for the energized electrons to fall back and give up their energy. These elements store energy and give off light slowly over a period of time. This is how glow-in-the-dark material works. Embedded in the material are atoms of the element phosphorus. When light energy hits the phosphorus atoms, some of the electrons absorb energy. When the electrons fall back, they releasethe stored energy and the material glows. The glow stops when all the electrons have returned to the lowest energy level. The process is called photoluminescence. The word "photo" means light and the word "luminescence" means glowing.The answer is photoluminescence.
Why does one of my cats eyes glow and the other one doesn't?
No. In the dark, the eyes of animals, especially animals that are nocturnal, will reflect light and look like they glow. This is the same thing that causes your eyes to "glow" red when someone takes a photo with a flash.
Does the tube light glow with out starter and choke?
it will not glow
How do planets glow?
They don't glow. They reflect the light from the sun.
