Why are mirrors made up of silver?
the surface ejects more electrons such that it leaves the surface to shine enough and reflect light.
What happens to electrons in photoelectric effect?
When you shine a certain level of light wavelength on metal, you can knock electrons off the atoms of the metal. This phenomenon was explained by Albert Einstein in 1905, for which he received a Nobel Prize in 1921.
What happens to electrons in the photoelectric effect (apex)?

Two beams of light shine on a white screen where one beam shines through a pane of red glass and the other shines through a beam of green glass. What happens if the two panes of glass are placed .....?
No light will be produced.
How did the light bulb get better after thomas Edison invented it?
We now have better materials for the filament and for the gas in the bulb, making them shine brighter and last longer.
The fluorescent molecules will shine when exposed to?
ultraviolet light
When antiobodies to which a fluorescent molecule has been attached are used as probes the fluorescent molecules will shine when exposed to?
ulruaviolet lights !
How far do high beams shine?
the answer is approx, 350 feet. if they are standard head lights.
It is ok to shine your high beams into a car that is coming at you with his high beams on?
Actually, in most states it's against the law to do that. That's if you get caught doing it though.
You should use the high-beam headlights to see and to be seen. Even in foggy conditions use the high beams.?
Not true. Hi beam lights shine higher above the ground. They will reflect back at you from fog and make it harder to see. Low beams shine lower and are not reflected back at you.
Why do some tube light shine in the night even you off it?
The tube rod has Tungsten as its cathode. When the light is switched on tungsten heats up exciting the electrons of phosporent (fluorescent). Due to excitation and de-excitation of the electrons, light of particular wavelength is released which falls within our visible range. When we cut of the supply, the tungsten doesn't immediately cool off and so does the fluorescent powder on the inner sides of the wall of tube rod. Hence, the tube rd glows for few minutes even after we switch it off.
When driving in fog use high beams?
You should never use high beams when you are driving in fog because they shine up and ahead which will be reflected straight back into your eyes by the fog. Low beams (which aim downwards) and front fog lights (which are lower) are far better suited.
What are lustrous material?
The word you are searching for is "RAMIE"...
Why do the beams in your attic sparkle as if with gold dust when you shine a flashlight on them?
the sap or rosin came to the surface and dried to spheres that reflect their golden color.
Are mobile electrons in the metallic bond responsible for luster?
it gives it its shine
Does a flashlight emit one beam or many beams of light?
Depends on the flashlight, some have many bulbs which would probably shine brighter, or just one big bulb which depending on the bulb, might shine less bright.
Does the amount of light increase if more and more flashlight beams are combined into one beam?
I'm not sure what you mean by 'the amount of light', or how you might plan to 'combine' several beams. When more flashlights shine on a surface, the intensity of illumination on the surface increases.
