Discussion Overview

The discussion revolves around the nature of the force between two electrons in an electrostatic context, specifically whether this force is mediated by a photon and the implications of this mediation in terms of quantum mechanics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant, R Rosenthal, questions if the repulsive force between two electrons is mediated by a photon.
  • Another participant simply affirms that the repulsion is mediated by a photon.
  • Randy Rosenthal inquires about the wavelength of the photon that would mediate this electrostatic repulsion.
  • A later reply explains that the photon is a virtual particle, existing for a time constrained by the Heisenberg Uncertainty Principle, and discusses how to calculate the energy and wavelength of the photon based on the distance between the electrons and the speed of light.

Areas of Agreement / Disagreement

While there is an affirmation that the repulsive force is mediated by a photon, the discussion includes questions and calculations regarding the properties of this photon, indicating that multiple views and uncertainties remain regarding the specifics of the mediation.

Contextual Notes

The discussion involves assumptions related to quantum mechanics and the Heisenberg Uncertainty Principle, as well as the nature of virtual particles, which may not be fully resolved or agreed upon by all participants.

Is the repulsive force between 2 electrons---(as in an electrostatic situation)---mediated by a photon----?------R Rosenthal
 
Physics news on Phys.org
Yes.
 
any idea what wavelength the photon would be that would mediate the electrostatic repulsion----?---randy rosenthal
 
The mediator here, the photon, is a virtual particle and as such exists for an amount of time allowed by the Hesenberg Uncertainty Principle. Therefore the photon must satisfy, ΔE Δt ≥\hbar
To find this ΔE requires knowledge of Δt, which could be found using the distance between the electrons divided by the speed of light. Then use the above equation to solve for ΔE, from which λ can be found using ΔE = \frac{hc}{λ}
