What happens if you stop a photon?

What happens if you stop a photon?

When photons of that energy meet an atom, they can scatter and excite it to a higher level, thus the photon is absorbed and “dies”.

What happens when a photon is destroyed?

The simplest answer is that when a photon is absorbed by an electron, it is completely destroyed. All its energy is imparted to the electron, which instantly jumps to a new energy level. The photon itself ceases to be. The opposite happens when an electron emits a photon.

Can photon be destroyed?

Photons are easily created and destroyed. Unlike matter, all sorts of things can make or destroy photons. Similarly, when a photon of the right wavelength strikes an atom, it disappears and imparts all its energy to kicking the electron into a new energy level.

What would happen if a photon reaches the end of the universe?

It simply expands. And since we can see light from back to the beginning of the universe, which is some 14 Billon years, any photon we were to emit would never reach the current limit of the “edge” of the universe because it is expanding at near the speed of light. It would never, ever get there.

What can stop photons?

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.

Can you fuse photons?

Photons — massless particles of light long thought to not interact among one another — have been fused together to create a new state of matter that until now had only been theoretical, according to a new study published in the journal Nature.

Has anyone stopped light?

Scientists at the University of Darmstadt in Germany have stopped light for one minute. Back in 1999, scientists slowed light down to just 17 meters per second, and then two years later the same research group stopped light entirely — but only for a few fractions of a second.

What happens to a photon when it stops moving?

The catch is: when a photon stops, it doesn’t just stop moving, it stops existing. Photons always travel at the same speed, which we call c. This is a constant in the universe as far as we know. As long as a photon exists, it is moving at speed c. Photons interact with charged particles such as electrons.

How do photons travel through space without a destination?

There is no mechanism described in Physics for a photon to travel without a destination. Thus it is postulated that every single photon must arrive and transfer it’s energy. The fact that time stops for that process implies that there is a ‘determined end’ in *every*…

Are Photons trapped in the electron field?

But during the time that the light is “slowed down” or “stopped”, it doesn’t actually exist anymore. You cannot say that the photons are somehow “trapped in the electron field”, because a photon by definition is just energy in the photon field. Once the energy’s gone somewhere else, it’s no longer a photon.

Does time pass from the perspective of a photon?

Time genuinely doesn’t pass from the “perspective” of a photon but, like everything in relativity, the situation isn’t as simple as photons “being in stasis” until they get where they’re going.
