Does a photon age?
Yet despite this incredible journey, the photon itself experiences none of what we know as time: it simply is emitted and then instantaneously is absorbed, experiencing the entirety of its travels through space in literally no time. Given everything that we know, a photon never ages in any way at all.
Do photons ever stop moving?
No, it is not possible to stop a photon. Photons are always moving. They have a constant total energy and kinetic energy of ( p c ). The rest mass of photons is always zero which means they have zero rest energy.
Why do photons move at the speed of light?
Some people say that the reason a photon travels at light speed the moment it is created is because it is a massless particle, and therefore must always travel at the speed of light. All quantum objects are partly waves and therefore can have a speed the moment they are created.
Do photons decelerate when they travel around a massive object?
According to theory of relativity ,When light rays travels around the massive object,their path gets deflected.My Question is that whether this deflection causes some deceleration of photons or not? and how? No, the speed of light remains the same. Only the direction is changed.
How far can a photon travel at the speed of light?
Whenever there’s a “time effect” there’s a “distance effect” as well, and in this case we find that infinite time dilation (no time for photons) goes hand in hand with infinite length contraction (there’s no distance to the destination). At the speed of light there’s no time to cover any distance, but there’s also no distance to cover.
Does time slow down at the speed of light?
In order to move from one place to another always takes a little time, no matter how fast you’re traveling. But “time slows down close to the speed of light”, and indeed at the speed of light no time passes at all. So how can light get from one place to another?
How long does it take for photons emitted by the Sun?
Traveling at the speed of light, photons emitted by the Sun take a little over eight minutes to reach the Earth.
