What does light do in photoelectric effect?
light knocks electrons off metal ions << apex : )
What kind of Light does a candle give off?
candle light
How do atoms give off electromagnetic waves?
Atoms give off (emit) electromagnetic waves by electrons dropping to lower orbit levels from higher levels of orbit.
In the photoelectric what happens when light hits the metal?
electrons are knocked off atoms causing electricity to flow
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.
What do fast moving electrons give off?
light
Why do atoms give off light when they drop energy levels in an atom?
When electrons fall to a lower energy level, they give off energy in the form of light.
Things that give off light?
The sources of light are electrons. When electrons are exited to a higher energy state, they fall back to their base energy level and in doing so release a photon of light. Thus light is produced in conditions where atoms/electrons become excited - places that are hot.
Do all heated elements give off light in the visible spectrum?
no it depends on the energy level the electrons are jumping down to
When light strikes electrons.do the electrons reflect the light back?
Not quite. Remember that electrons are part particles and part waves. Light is given off when an electron drops from one energy state to a lower one. In answer to a different question, and may be the one you ask, When light strikes a phosphor, the electrons in the phosphor absorb energy, and give it off some time later. This is Phosphorescence.
Does Uranus give off light?
yes it does give off light
What does give off light mean?
The phrase 'give off light' means to have a lot of light.
What does the light do to the electrons found in the chloroplast?
They give energy to electrons.So electrons become exited.
Does Neptune or its moons give off light?
Planets and Moons only reflect light, they do not 'give off light'.
What light rose give?
A rose does not give off light
What does light do in photoelectric effect?

What bodies in your Galaxy give off or reflect light?
The stars give off light
