Interference of Light: Perpendicular Beams

Click For Summary

Discussion Overview

The discussion centers on the interaction of two beams of light that pass through each other perpendicularly. Participants explore the nature of light, particularly whether photons can interact with one another under these conditions, and the implications of coherence in the beams.

Discussion Character

  • Debate/contested

Main Points Raised

  • One participant asserts that nothing happens when two beams of light intersect perpendicularly, as light does not interact with itself.
  • Another participant agrees with this view but mentions a counterargument from someone else, indicating uncertainty about the interaction of light.
  • A different participant suggests that photons can interact, but only under specific conditions and with difficulty, referencing a scientific paper for further reading.
  • It is noted that the coherence of the beams may influence their interaction, but two perpendicular beams would not be affected due to the orientation of their field components.

Areas of Agreement / Disagreement

Participants express differing views on whether photons can interact with each other, leading to an unresolved discussion regarding the nature of light and its interactions.

Contextual Notes

Some assumptions about the conditions under which light interacts, such as coherence and the nature of the beams, remain unaddressed. The discussion does not resolve the complexities of photon interactions.

what happens when two beams of light pass through each other perpendicular to each other??
 
Science news on Phys.org
Nothing: light (photons) does not interact with itself. Thus the two lightbeams will simply go strait through each other.
 
yah that's what i thought but this guy i know said i was wrong. thanks.
 
It depends if the beams were coherent or not. But two beams passing perpendicularly wouldn't be affected either way as the field components would be in the wrong directions
