Comments on: Is possible to light freq. from blue to red and green to red using lenses? If so where can get some of them? http://greenhappensnow.com/is-possible-to-light-freq-from-blue-to-red-and-green-to-red-using-lenses-if-so-where-can-get-some-of-them/141/ Green Resources for the Renewable Energy Lifestyle Fri, 18 May 2012 13:00:37 +0000 http://wordpress.org/?v=2.7.1 hourly 1 By: Dr. R http://greenhappensnow.com/is-possible-to-light-freq-from-blue-to-red-and-green-to-red-using-lenses-if-so-where-can-get-some-of-them/141/comment-page-1/#comment-134 Dr. R Sun, 26 Oct 2008 04:30:53 +0000 http://greenhappensnow.com/is-possible-to-light-freq-from-blue-to-red-and-green-to-red-using-lenses-if-so-where-can-get-some-of-them/141/#comment-134 <a href=""></a> Not with lenses. There are phosphors that do that, but they are not very efficient.

The only way to change wavelength is to have an object moving quickly towards or away from the source - and even then, only slightly.
