I provided the reference a number of times and you
chose to ignore it. The reference is the chapter on
interference in "Optics", by Hecht.

I am suprised that a book on optics would discuss the
output impedance of Thevenin equivalent circuits.

Be that as it may, could you kindly provide the brief
extract from "Optics", by Hecht, that clearly states
that the impedance in a Thevenin equivalent circuit
can not be used to compute the reflection coefficient.
