Feynman Diagrams: Does Distance Affect Electromagnetic Interaction?

In summary, Feynman diagrams are a visual representation of mathematical terms and are not meant to explain the mechanics of particle behavior. Virtual photons are used as calculational tools and their creation and interaction are dependent on the distance between particles.

Hello all .
In feynman diagram horizontal direction is space . is that mean distance between particles ?
is that means two electron must be near a certain distance to create a virtual photon ?

Does one electron in Earth send electromagnetism force to one electron on moon by virtual photon ?
Does one electron in Earth has interaction with one electron on moon by electromagnetism force ?

Does virtual photons create in short distance ?
Creation of virtual photon depend on distance between two particles ?

Feynman diagrams are convenient shorthand for terms in a mathematical expression. They are not meant to be an underlying "billiard ball" mechanics of particle behavior.

virtual photons are calculational tools,that is why they are called virtual.
 

1. How do Feynman diagrams explain electromagnetic interaction?

Feynman diagrams are a visual representation of quantum mechanical interactions between particles. In the case of electromagnetic interaction, the diagrams show the exchange of virtual photons between charged particles, which is the mechanism by which electromagnetic forces are transmitted.

2. Do Feynman diagrams take into account the distance between particles?

Yes, Feynman diagrams do take into account the distance between particles. The distance between the particles is represented by the length of the lines connecting them in the diagram. The shorter the distance, the stronger the interaction between the particles.

3. How does distance affect the strength of electromagnetic interaction?

The strength of electromagnetic interaction is inversely proportional to the square of the distance between the particles. This means that the closer the particles are, the stronger the interaction will be.

4. Can Feynman diagrams be used to calculate the strength of electromagnetic interaction?

Yes, Feynman diagrams can be used to calculate the strength of electromagnetic interaction. By analyzing the diagram and using mathematical equations, physicists can determine the strength of the interaction between particles at a specific distance.

5. Do Feynman diagrams only apply to electromagnetic interactions?

No, Feynman diagrams can be used to represent and calculate interactions between particles in all of the fundamental forces of nature, including the strong and weak nuclear forces as well as gravity.
