Re: Dry "wet" roads

[Bernard Cleyet <anngeorg@PACBELL.NET>]

This thread has almost convinced me to stop buying books.  The eight pages of
photo's and explanation in "Color and Light in Nature" (Lynch & Livingston)
are not as complete and striking as those found using Google (JD's for
example).  However, a naive search won't quickly reveal the existence of
lateral (mural) mirages.

Incidentally do the students mean by wet, the lustrous appearance such a mirage
appears as similar to a prism's total internal reflection?  JD's site argues
that all mirages are more properly refractions than internal reflection.  When
is a boundary diffuse enuff for the reflection to be called refraction?
