Photon Interaction with Environment at Long Range

Click For Summary
SUMMARY

Photons interact weakly with their environment over long distances due to their fundamental properties and the nature of electromagnetic interactions. While the term "weakly" may vary in interpretation, photons can exhibit significant interactions in specific contexts. In contrast, neutrinos are identified as particles that require the weak force for interaction, making them even less likely to engage with their surroundings compared to photons.

PREREQUISITES
  • Understanding of electromagnetic interactions
  • Familiarity with particle physics concepts
  • Knowledge of the weak force and its role in particle interactions
  • Basic comprehension of photon behavior in various mediums
NEXT STEPS
  • Research the properties of photons in different environments
  • Study the weak force and its implications in particle physics
  • Explore the behavior of neutrinos and their interactions
  • Investigate advanced topics in quantum electrodynamics
USEFUL FOR

Physicists, students of particle physics, and anyone interested in the fundamental interactions of light and matter.

Well, "weakly" is in the eye of the beholder. You can do a lot of different things with photons where the interaction does not seem weak at all. And you can have other particles (electrons, protons, atoms) that travel without much interacting with the environment as well.

In my book, neutrinos are the ones that are hard to interact with. Requiring of course the weak force.
