Eye's response to electromagnetic (light) waves?

Click For Summary

Discussion Overview

The discussion revolves around how the eye's retina, specifically the rods and cones, responds to electromagnetic (light) waves. Participants explore whether the detection involves the electric (E) or magnetic (B) components of light, or if it is better described through photon interactions.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification

Main Points Raised

  • One participant questions whether the eye detects the electric or magnetic components of light waves.
  • Another participant suggests that the interaction is better understood in terms of photons rather than classical wave descriptions.
  • A different viewpoint is presented that the eye detects photon energy rather than electromagnetic fields, emphasizing the rapid oscillation of these fields in the visible range.
  • A participant acknowledges the importance of using the term "photoreceptor" and expresses appreciation for the information provided in a linked article.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether the eye detects E or B components, or if photon interactions are the more appropriate framework. Multiple competing views remain regarding the nature of the detection process.

Contextual Notes

There is a lack of clarity regarding the definitions of terms used, such as "photoreceptor" and the distinction between photon energy and electromagnetic fields. The discussion also highlights the complexity of the eye's response to rapidly changing electromagnetic fields.

It's a photon (quantum) interaction so that's the best way to describe the event, rather than in terms of waves.
 
I believe the eye detects photon energy, not EM fields. If you don't like photons, then the eye responds to the average energy deposited by the EM fields. Don't forget that in the visible range these fields change direction about 1014 times a second. Did you come across this article when you searched?

Thanks for the quantum and wikipedia comments. Since I didn't use the word photoreceptor I wasn't successful. I guess I was too Maxwellian. That wiki article is fascinating along with the great illustrations. Now I can really appreciate my vision.
