Discussion Overview

The discussion centers on the nature of light and its movement, specifically examining the wave theory and particle theory of light. Participants explore how light behaves according to these theories, including whether photons physically move as waves or in straight lines, and the implications of oscillating electric and magnetic fields.

Discussion Character

  • Exploratory
  • Debate/contested
  • Conceptual clarification

Main Points Raised

  • One participant questions whether photons physically move as waves or if they travel in straight lines, suggesting a need for clarification on the wave theory and particle theory of light.
  • Another participant asserts that light is fundamentally made of photons, which exhibit both particle-like and wave-like behaviors, indicating a lack of conflict between the two theories.
  • A follow-up response seeks to clarify that the inquiry is not about conflict but rather about the implications of the photon theory regarding the movement of light as a wave.
  • Further clarification is requested on whether the reference to wave movement pertains to the physical movement of photons or the behavior of electric and magnetic fields.
  • A participant mentions the complexities of light movement in fiber optics, suggesting that the wave nature of light may contribute to these complexities.

Areas of Agreement / Disagreement

Participants express differing views on the nature of light's movement, with some emphasizing the photon theory while others seek to understand the implications of wave behavior. The discussion remains unresolved with multiple competing perspectives.

Contextual Notes

There are limitations in the discussion regarding the definitions of wave and particle theories, as well as the assumptions about the physical movement of photons versus the behavior of fields.

Light has two theories, wave theory and the photon theory.

My one main doubt is that, do photons physically move as a wave. Or do photons travel in straight lines but just have the ability to bend here and there; even in the wave theory, does light move physically in a wave-like manner, or is it just the existence of oscillating electric field and magnetic field which change in a wave-like manner at a place telling us that it is the wave theory.

Could anyone explain how light moves according to the wave theory and the particle theory of light in brief.

No, light only has one theory: light is made of photons. Photons share some behaviors with (classical) particles and some with waves, but there is no either/or conflict.
 
I did not refer to a conflict rather my main doubt was whether the photon theory says that light moves as a wave.
 
Like physically move as moves. Or is it just referring to the electric and magnetic fields inside.

I'm not a professional physicist but I know that the way light moves through a fiber-optic is pretty hairy. Light phases in and out. This might have something to do with the wave nature of light. I know it gives fiber-optic technicians a hard time.
