THE INTERNAL REFLECTION OF MONOCHROMATIC LIGHT
ON SUPERFICIAL FILMS ON SOLID SUBSTRATES
Internal partial or total reflection present similitude and differences with
external reflection depending on the incidence angle of the light. Total reflection
has a major theoretical importance because complex aspects concerning the
interaction between light and superficial film. Both the analysis of the
parameters that decide upon the type of reflection and the manner of
interaction of the light with superficial films allow correct interpretation of
experimental measurements. Internal attenuated total reflection is one method
of investigation “in situ” of superficial films illustrated in this paper.
