Nowhere. A photon must travel at the speed of light so it starts with that speed when it is created. This is the origin of the theory of special relativity.
Yes, a photon moves at the speed of light, because photons have no mass.
No, a photon always moves at the speed of light, and nothing with non-zero mass (which includes neutrons) can move that fast
You need to know the photon's frequency or wavelength. If you know the wavelength, divide the speed of light by the photon's wavelength to find the frequency. Once you have the photon's frequency, multiply that by Planck's Konstant. The product is the photon's energy.
In a vacuum, a photon can ONLY move at the speed of light. A regular particle can ONLY move at speeds less than the speed of light.
Only if you are a photon. In that case, you always move at the speed of light. If you're not a photon, and have any mass while you're sitting still, and are not moving at the speed of light right now, then you can never attain light speed.
299 792 458 m / s, and the speed is the same for a photon (this speed is in a vcuum)
Under the photon theory of light, a photon is a discrete bundle (or quantum) of electromagnetic (or light) energy. Photons are always in motion and, in a vacuum, have a constant speed of light to all observers, at the vacuum speed of light (more commonly just called the speed of light) of c = 2.998 x 108 m/s.
yes, exemple; photon and electricity
Another photon approaching at the speed of light. Photons have no sensory organs so they cannot "see" anything.
A photon is a massless particle, meaning it has no rest mass. Its mass is zero, but it does have energy and momentum.
A photon is said to be "massless", meaning that it has no REST MASS (of course, having energy, it also has an equivalent mass).In a vacuum, a photon can ONLY move at the so-called speed of light (about 300,000 km/second). "Regular" particles can ONLY move at sub-light speed. They can get close to the speed of light, but never quite reach it.
