Talk:Incident light

I have no problem it redirects to Ray, but in that article, the term "incident light" is not mentioned. What is explained is an incident ray. So I propose to mention that incident light is "incoming light". But where? In the redirect page, below where is the redirect code? Or in the article on "Ray"? Or is it better to make a link to the wiktionary? Thx --SvenAERTS (talk) 10:41, 9 August 2011 (UTC)
 * Wikipedia is not a dictionary, so it isn't appropriate to create an article just to give a definition of a term. Usually, definitions can be provided by linking to Wiktionary, like this: incident. A better approach is to rephrase the article that uses the term, so that it either explains the term in the article, or does not use that term.--Srleffler (talk) 02:25, 10 August 2011 (UTC)
