Can photons affect each other's trajectories?

In summary, photons can interact with each other through scattering or absorption and re-emission, which can affect their trajectories. This can occur through photon-photon scattering, where two photons collide and can either scatter off in different directions or merge into a single photon. The degree of interaction depends on the photons' energy and the type of matter they interact with. The interaction is not instantaneous as it takes time for photons to interact and affect each other's trajectories, limited by the maximum speed of light.

Greetings,

Can photons affect each others' trajectories like other particles do when they encounter each other?

Thanks

Yes, but the effect is extremely weak.
See "Delbruck scattering".

for your question. The behavior of photons is quite different from that of other particles, as they are massless and have no charge. Therefore, they do not interact with each other in the same way that other particles do. Photons can pass through each other without affecting each other's trajectories. This is because they are governed by the laws of electromagnetism, which state that they only interact with charged particles. However, photons can be affected by other particles, such as electrons, which can absorb or scatter them, changing their direction and trajectory. So while photons do not directly affect each other's trajectories, they can still be influenced by other particles in their environment. I hope this helps answer your question.
 

1. Can photons interact with each other?

Yes, photons can interact with each other through the process of scattering or absorption and re-emission. This interaction can affect the trajectory of photons.

2. How do photons affect each other's trajectories?

Photons can affect each other's trajectories through the process of scattering. When two photons collide, they can either scatter off in different directions or merge into a single photon with a different trajectory. This interaction is known as photon-photon scattering.

3. Can photons change the direction of another photon's trajectory?

Yes, photons can change the direction of another photon's trajectory through scattering. This is due to the photons exchanging momentum during the interaction, causing a change in the direction of their paths.

4. Do all photons interact with each other in the same way?

No, not all photons interact with each other in the same way. The degree of interaction between photons depends on their energy and the type of matter they are interacting with. For example, high-energy photons are more likely to undergo photon-photon scattering compared to low-energy photons.

5. Is the interaction between photons instantaneous?

No, the interaction between photons is not instantaneous. It takes a finite amount of time for photons to interact and affect each other's trajectories. This is due to the speed of light, which is the maximum speed at which any interaction can occur.
