The most practical application is fluorescence. By passing electricity through a gas, you "excite" the electrons in the atom. Atoms "prefer" to stay at lower levels of energy. In order for the atom to lower its energy, it gives out light in photons.
Because of this phenomenon, we can make neon signs, fluorescent light bulbs and even find the chemical make up of different objects using spectroscopy.
A typical person probably has seen a neon sign at a bar and nowadays we have stopped using incandescent light bulbs and moved to the more efficient CFLs. (CFLs are about 4 times more energy efficient than light bulbs.) Mercury is the most prominent element in CFL bulbs and when excited, the atoms give off photons of light that are red, green and blue. The mixing of these colors give us white light. Mercury also gives off photons in the ultraviolet spectrum, which is invisible. The light bulb has a special coating that takes the energy of the UV photon and gives off a different photon in the visible light spectrum. This is why CFLs seem to have a blue tint to them.
What else can I help you with?
Will pencil lead conduct electricity?
Yes, Pencil Lead does conduct Electricity. Copper, Gold and Silver though are the best conductors.
When did Victorians first use electricity?
the Victorians didn't use electricity but the light bulb did and it was the only thing that did. electricity
How do you get rid of electricity in your hair?
If you mean static electricity which makes the hair "poof" then squeezing the hair using your hands and blowing on it can help. Don't brush it though that usually makes it worse.
How does Electrical Energy help us?
Electricity was discovered not invented. Without it our lives would be more difficult though.
An advantage of off-peak electricity?
For the electricity companies the advantages are : - Transformers dont damage (Transformers are most efficient at full load) - Constant use of electricity meaning that theres no need for storing electricity (even though its near impossible to store AC) For the customer the advantages are: - Cheaper Electricity at off peak times. (the reason its cheaper is to encourage people to use off peak more so that the transformers run at maximum efficiency - hence not damaging them)
How is heat made by electricity?
There are many ways how electricity can create heat. For example, passing a current through a wire of high resistance (i.e. a resistor) will generate heat, though not much.
Why Rain water not passing voltage?
Pure water, like rain, does not conduct electricity. Some rain, though it may not be not pure water, and may be a little acid, or have dust in it, could conduct electricity a tiny amount.
Is acid a part of electricity?
Acids are not part of electricity, though acids can conduct electricity.
Why is there electricity in the energy drinks?
There is no electricity 'in' energy drinks. Though electricity will have been used in the manufacture of them.
Is heat is a form of electricity?
technically no, electricity is a form of heat though
Did they have electricity in the 1900s?
On September 4, 1882, the first commercial power station, located on Pearl Street in Lower Manhattan, went into operation providing light and electrical power to customers in a one square mile area.
What is the most secure and practical means of providing remote LAN access for this application?
For a single application, SSL VPN can be very good because it allows very specific access control. SSL VPN hardware can be pretty expensive, so IPSec VPN is a good alternative, though generally more permissive.
What is the combine word for science and technology?
There is no combined word for these two words. But the technology is usually application of scientific knowledge for solving practical problems. Though many times technology was developed without a complete understanding of the underlying principles.
What metals will electricity pass though?
A conductor
Is mica conductor?
Mica is not a conductor of electricity. It is actually an insulator, meaning it does not allow electricity to flow through it easily. Mica is often used in electrical and electronic applications as an insulating material to prevent current flow.
Does the printer have electricity?
The printer by itself does not contain electricity. When plugged in, however, it does contain electricity. As soon as the plug is pulled, though, it does not have it anymore.
What is the antonym of application?
The synonym of application may be un-application if that's a word. I am not sure though and I am still looking for an appropriate answer myself.
