Description:

This module is used to teach physics to a group of 2nd year students, and
 illustrates the transmission and reflection of electromagnetic waves from
 transparent media.  The transparency of the media represents
 the magnitude of their
refractive indices, which can be altered.
The incident angle may be changed and
all other angles, reflection and transmission coefficients, amplitudes
 of waves, phase changes etc are calculated and diplayed.  The waves propagate
when the animate button is clicked.  Interesting physical effects such as the
Brewster angle may be demonstrated.
