uhh - in explaining photoelasticity, you state "When these two waves meet and recombine they produce a
polarization unique to that color" According to other web pages on the subject, the two waves emerge from the
plastic, each being confined to its own plane of polarization and these two planes are perpendicular. Thus it is
the second sheet of polaroid - the analyzer, that produces light confined to a single plane of polarization and thus
permits interference of the two waves.
