Bob_for_short Posted September 20, 2009 Author Share Posted September 20, 2009 he never said there was a dependence on the number of photons. Me neither. Well, I am disappointed and tired. I quit this conversation. Cheers. Link to comment Share on other sites More sharing options...
insane_alien Posted September 20, 2009 Share Posted September 20, 2009 then why did you bring it up in your response? Link to comment Share on other sites More sharing options...
Klaynos Posted September 20, 2009 Share Posted September 20, 2009 If the light propagation depended on number of photons, it would be a non-linear effect. It exists indeed but at very high intensities. So the linear, usual theory of light propagation is valid for any number of photons, even for one. The explanation not the overall effect. Interestingly though non-linear effects with light propagating through media is quite common, [math]\chi^{(2)}[/math] and [math]\chi^{(3)}[/math] happen in most materials with a measurable effect if you use high enough intensities.

swansont Posted September 21, 2009 Share Posted September 21, 2009 Shame on you. This commentary is inappropriate Again' date=' speaking of absorption and re-emission as a reason for delay is wrong and it is you burden to learn when you were told so.[/quote'] Asking for references to back up claims is a proper request Link to comment Share on other sites More sharing options...
