Light in vacuum and inverse square law

Click For Summary

Discussion Overview

The discussion centers on the application of the inverse square law to light in a vacuum, exploring whether this principle is applicable and how it is represented in various sources.

Discussion Character

  • Conceptual clarification, Debate/contested, Meta-discussion

Main Points Raised

  • Some participants assert that the inverse square law does apply to light in a vacuum.
  • One participant expresses uncertainty about finding reliable references to confirm this information, noting that Wikipedia does not explicitly mention it in relevant articles.
  • Another participant points out that the inverse square law is indeed mentioned in the introduction of the Wikipedia article on the topic.
  • A later reply emphasizes the importance of proper attribution when using external sources, highlighting concerns about copyright and the ethical practice of crediting original authors.

Areas of Agreement / Disagreement

While some participants agree that the inverse square law applies to light in a vacuum, there is uncertainty regarding the availability of references to support this claim. The discussion includes both agreement on the principle and a lack of consensus on sourcing.

Contextual Notes

Participants express varying levels of familiarity with the topic and the reliability of sources, indicating potential limitations in their understanding or access to comprehensive information.

Yes.

Thanks. I tried to google but I couldn't confirm it, and Wikipedia does not mention it in either "photon" or "light" articles. Would you know what should I google for so I can find some references about it?

Just went there for the picture, and was stupid enough not to read it. Funny!

Please note that if you took something from another source, you must attribute it to that source, or else you are stealing something! Worse still, some of these things might be copyrighted, and WE might get into a whole of trouble without making at least proper references to the sources.

Besides, it is just good practice (and manners) to give credit where credit it due.
