Photons are the carriers of the electromagnetic force. Photons always come in "wavelengths." These wavelengths differ from gamma rays (wavelength 10-12 meters) to ELF (extremely low frequency) radio waves (wavelength 100000 kilometers). Visible light ranges from 390 to 750 nm (nanometers, or 10-9 meters).
Photons are also the reason positive and negatively charged particles attract, as gluons are the reason different color charges attract. These attractions are caused by the exchange, or swapping, of the gluons or photons, classified as "gauge bosons", between two particles that interact via any force. Gauge bosons, in definition, are the carriers of forces. Other gauge bosons are, as mentioned earlier, the gluon (the carrier of the strong force, or color charge), the W and Z bosons (they both are carriers of the weak force, but the Z is neutral, and the W can be charged), and the hypothetical "graviton", or the carrier of gravity.
The "wave-particle" theory is a hard concept to understand. I've heard from Steven Pollock, on a CD I bought, an excellent explanation. He says," All forces have a "field." When you "jiggle" this field, it creates a ripple, like a rock thrown in a pond does. This ripple, if in the electromagnetic field, is the photon."
Photons also carry different amounts of "eV", or "electron volts", like other particles. Mass of particles is also measured in eV. If a photon is carrying, say, 1.022 MeV (mega electron volt), it could, at any given time, turn into a positron and an electron. This matter-antimatter pair annihilates, and releases a photon carrying the same amount of energy, 1.022 MeV, or maybe a series of particles with 1.022 MeV/c2 (from E=mc2) worth of mass. The mass of each of these particles (the positron and electron) has to be 5.11 MeV/c2, or half of 1.022 MeV. The mass of the proton is .938 GeV (giga electron volt)/c2. So when a proton and an antiproton collide and annihilate, they release a photon with 1.876 GeV, a series of particles with 1.876 GeV/c2 worth of mass, or a combination of the two.
A photon is a particle of electromagnetic radiation, for example a gamma ray, x-ray, light, etc.
A quantum of electromagnetic radiation; an elementary particle that is its own antiparticle
A packet of light energy is called a photon.
Assuming the photon is reflected into the same medium it came from (so we can ignore refraction), its momentum differs only directionally, its magnitude stays the same. The directional component of its momentum vector is always pointing in the direction it's propagating. Refraction is the means by which the magnitude component of the vector changes. The change in momentum of photon is nh/lambda.

Compton scatter: Interaction between an incoming X-ray photon and an outer-shell electron results in the photon changing direction. Photoelectric effect: Absorption of X-ray photon by inner-shell electron leading to emission of a secondary photon. Pair production: High-energy X-ray photon interacts with atomic nucleus, creating an electron-positron pair. Rayleigh scatter: Low-energy X-ray photon interacts with an atom without ionization, resulting in a scattered photon with the same energy.
To arrange photons in order of increasing energy, you can use the equation E = hf, where E is the energy of the photon, h is Planck's constant, and f is the frequency of the photon. Photons with higher frequency will have higher energy. So, simply compare the frequencies of the photons to determine their energy order.
A photon's energy is the amount of electromagnetic radiation it carries, determined by its frequency. In quantum mechanics, the energy of a photon is proportional to its frequency through Planck's equation, E = hf, where E is energy, h is Planck's constant, and f is frequency.
The measure of a photon's energy is its frequency or equivalently, its wavelength. This is determined by the amount of energy carried by the photon, corresponding to the electromagnetic spectrum as visible light, radio waves or X-rays depending on the energy level.
A packet of light energy is called a photon.
The energy of a photon is inversely propotional to its wavelength. The wavelength of a blue photon is less than that of a red photon. That makes the blue photon more energetic. Or how about this? The energy of a photon is directly proportional to its frequency. The frequency of a blue photon is greater than that of a red photon. That makes the blue photon more energetic. The wavelength of a photon is inversely proportional to its frequency. The the longer the wavelength, the lower the frequency. The shorter the wavelength, the higher the frequency.
The opposite of a photon is an antiphoton.
Photon flux can be calculated using the formula: photon flux = v * E, where v is the frequency of the photons and E is the energy of each photon. By multiplying the frequency of the photons by the energy of each photon, you can determine the photon flux.

No, a photon is not time travelling

To increase the momentum of a photon, you can either increase its frequency or velocity. This can be achieved by changing the energy of the photon, as momentum is directly proportional to the energy of a photon.
