  Photon - Wikipedia, the free encyclopedia
The photon is one of the elementary particles.
The energy and momentum carried by a photon is proportional to its frequency (or inversely proportional to its wavelength) with a constant of proportionality equal to the Planck constant.
Photons are deflected by a gravitational field twice as much as Newtonian mechanics predicts for a test mass traveling at the speed of light.

 Photon torpedo - Wikipedia, the free encyclopedia
Photon torpedoes are most useful for combat while ships are engaged in warp speed travel, as phasers, which are confined to the speed of light, are not generally usable.
A typical photon torpedo is an elongated elliptical tube that measures 2.1 m in length, 0.76 m in width, 0.45 m in height, and 247.5 kg in dry mass.
Photon torpedo casings are known to be extremely tough, capable of surviving intact high-speed entry into the atmosphere of an M-class planet.

 Photon
Photons are often loosely associated to light, to which they relate only for a very narrow frequency window of the spectrum.
Even there, light is commonly encountered in quantum states which are not pure photons but superpositions of different numbers of photons, to wit, either coherent superpositions (so-called coherent states) describing coherent light such as the one emitted by an ideal laser, or chaotic superpositions (so-called thermal states) describing light in thermal equilibrium (flbody radiation).
The dispersion relation is linear and the constant of proportionality is Planck's constant h, yielding the useful relations for kinematic studies, E = h ν (with E the photon energy and ν the frequency of the mode, or photon frequency) and p = h ν / c (p the momentum).

 Photon Belt - Crystalinks
A photon is a quantum of light, or the smallest possible packet of light at a given wavelength.
Because a single photon may stimulate the release of a large number of additional photons, the total number of photons is increased, thus increasing the intensity of the light within the medium.
The Photon Belt is a belief largely linked to some parts of the new age movement that a band of photons is going to collide with the Earth and cause massive failure of electrical equipment.

 photon on Encyclopedia.com
PHOTON [photon], the particle composing light and other forms of electromagnetic radiation, sometimes called light quantum.
About the beginning of the 20th cent., the classical theory that light is emitted and absorbed by matter in a continuous stream came under criticism because it led to incorrect predictions about several effects, notably the radiation of light by incandescent bodies (see fl body) and the photoelectric effect.
The light imparts energy and momentum to a charged particle when one of the photons collides with it, as is demonstrated by the Compton effect.

 PHOTON EMISSION   (Site not responding. Last check: 2007-10-21)
Since a photon is described subsequently as a quantum of space, the photon may also be a type of distortion of this same space and time, a compact highly-curved region of space--a type of localized wave in space-time.
Photons are produced as the wave vectors are up and holes are produced when they are in the down direction in the image.
The two varieties of photons (photons and photon holes) proposal is probably not directly testable, however, symmetrical reasoning indicates that this should indeed be the case.

 Origin of the word "photon"   (Site not responding. Last check: 2007-10-21)
The serious objections to the idea of the conservation of photons are met in a consideration of the thermodynamics of radiation and of the laws of spectroscopy.
If, therefore, we are to admit the conservation of photons, we must say that the atom does not pass from precisely the same initial to the same final state by the two paths, but rather that either the 4-2 or the 1-1 states must be multiple.
To account for the apparent existence of these processes, it is necessary to assume that atoms are frequently changing their photon number by the exchange of photons of very small energy, corresponding to thermal radiation in the extreme infra-red.

 Monica Rambeau - Wikipedia, the free encyclopedia
Monica was known as Captain Marvel for most of her Avengers career; however, she agreed to change her alias to Photon, conceding the Captain Marvel title to Genis-Vell, the son of the original Captain Marvel, out of respect for her predecessor.
In the Black Panther series by Reginald Hudlin, Monica Rambeau is recruited by the Black Panther to fend of a vampire outbreak in post-Katrina New Orleans, as part of an all-fl super hero team comprising Luke Cage, Blade, Black Panther and Brother Voodoo.
She can turn into photons (light), electricity, microwaves, radio waves, ultra-violet rays, gamma rays, or any known form of energy from the electromagnetic spectrum; by focusing her light-energy form into a tight beam, she can become a laser.

 CERN Courier - Photon teleportation achieve - IOP Publishing - article
For example, with two entangled photons (A and B), determining the polarization of one of them (say, 0°) automatically defines the polarization of the other _ the second photon must "collapse" into the complementary state (90°).
Therefore to teleport the information "45° polarization", a messenger photon of 45° polarization is made to entangle with photon A, thus obliging A then to be in the complementary polarization state.
This in turn means that photon B now has the same polarization as the messenger photon, which is complementary to that of A. Then measuring the 45° polarization of B means "message received".
