t
Phase after bounce higher by
Note t is used in the text both for the
thickness and the transmission coefficient!!!!!!!

So the successive outgoing waves will be
Note that your text is suppressing kx in
the phase and reversing the sign of the phase -gt
positive ?t rather than negative- making delta
come in with minus sign.
