photon

 [fo´ton]
a discrete particle (quantum) of radiant energy.

pho·ton (hν, γ),

(fō'ton),
In physics, a corpuscle of energy or particle of light; a quantum of light or other electromagnetic radiation.

photon

(fō′tŏn′)
n.
The elementary particle of light and other electromagnetic radiation; the quantum of electromagnetic energy. The photon is the massless, neutral vector boson that mediates electromagnetic interactions.

pho·ton′ic adj.

pho·ton

(γ) (fō'ton)
physics A corpuscle of energy or particle of light; a quantum of light or other electromagnetic radiation.

photon

a quantum of radiant energy with a wavelength in the visible range of the ELECTROMAGNETIC SPECTRUM.

Photon

A light particle.

photon 

The basic unit of radiant energy defined by the equation
E = hν
where h is Planck's constant (6.62 ✕ 10−34 joule ✕ second), ν the frequency of the light and E the energy difference carried away by the emission of a single photon of light. The term photon usually refers to visible light whereas the term quantum refers to other electromagnetic radiations. See quantum theory; wave theory; troland.

pho·ton

(γ) (fō'ton)
In physics, corpuscle of energy or particle of light; a quantum of light or other electromagnetic radiation.

Transferring data using light passed along fibre optic cables has become increasingly common over the past decades, but each pulse currently contains millions of photons. That means that, in principle, a portion of these could be intercepted without detection.
Theoretical and computational aspects of the inclusive isolated prompt photon production such as involved leading order (LO) and next-to-leading order (NLO) subprocesses, direct and fragmentation component of the cross section, and photon isolation requirement have been discussed in many papers (e.g., see [30, 32]).
The scientists injected photons one at a time into an interferometer.
The purpose of the paper is to present a model view of the photon by obtaining a three-dimensional solution from Eqs.
With regard to this issue, we developed a photon detection system that has high quantum efficiency (988%) and is able to discriminate the number of incident photons.
Of course, the cumulative effect of absorbing lots of cell tower photons would be to raise the temperature of your cells.
