How are photons created???

Answer 1

Photons are light waves or particles given off by the excitation of certain elements. A good example is a LASER, a flash tube "pumps" the doped crystalline base, thereby exciting certain atoms into reaching a higher energy state, the results are photons being released.

SEE: http://en.wikipedia.org/wiki/Photons for an accurate and complete explanation :)

Answer 2

Photons are packets of energy which are emitted whenever an electron in an excited states falls to a lower energy level. The excitation may have been caused by the transferrence of energy to it from radiation hitting it or through heating.

For the electron then to fall to the lower energy level, it as to give out that energy in one way or another. One of the ways it dissipates this energy is by giving it out in the form of light.

Now the difference between energies of two consecutive energy levels is hf. It is this difference in energy that is then emitted as a photon. Therefore a photon has an energy of hf, where h = planck's constant and f is the frequency of the radiated light.

I hope this helps

Answer 3

When electrons drop to a lower energy band on the atom they inhabit they produce a photon (the energy freed by the level change).

Answer 4

A photon is created when an electron jumps from a higher energy level to a lower one.

Answer 5

Anytime you accelerate a charge, you generate a time varying electric field which in turn generates a time varying magnetic field. Because one field generates the other, you get propogating electro-magnetic radiation, AKA light.

I have not studied the production of photons within atoms in detail, however the change of an electron's probability distribution as it moves from one orbital to another will certainly change the electric field associated with the electron. It is not much of a stretch to think that this change in electric field will generate an EM "wave. "

In practice this occurs when an electron "falls" from a higher energy level to a lower energy level, though as I stated above, free charges can make other kinds of EM radiation.

A photon is simply the particle manifestation of an EM wavicle.
