Talk:Antifilter

Despite the assumptions of some other editors, there is no evidence that there is any wave plate here. If you put an ordinary polarizer at 45° between two crossed polarizers, you will observe transmission. This is a feature of the transverse wave nature of light. No wave plate is required. No quantum mechanics is needed either; the effect is entirely classical. It is relevant to quantum mechanics, in that this wave property has analogues in quantum physics. --Srleffler 07:03, 3 November 2006 (UTC)

What are you talking about? I just tried it with some glass polarizers here and did not get increased transmission. Of course, the claims of it being a result of quantum mechanics is nonsense.... I'm disappointed that you restored the unprofessional language of "An amazing experiment in optics" etc. --Gmaxwell 19:24, 3 November 2006 (UTC)

oh sure enough, indeed it does. Yes, thats probably what this is. My mistake. --Gmaxwell 19:33, 3 November 2006 (UTC)

This is quantum physics, because light is a quantum phenomenon. It is true that classical electromagnetism explains also the antifilter effect, but this does not change the fact that light is truly quantum, and that the quantum explanation is better, because it is universal. --Thierry Dugnolle (talk) 13:14, 13 March 2017 (UTC)
