The following about speed of light changes in various
mass was posted to the vort list;

Hi Gary et al!
Speed of light does differ but restores its speed when
it exits;
http://wigner.byu.edu/LightRefract/LightRefract.html
There is a comment in an old book that 'light can be
made to yield sound'...waves successively divided
would do that...
Years ago, a few of us were thinking along the lines
of having various refractory substances coupled
together for the express purpose of slowing light down
in stages, eventually to reach something
useful...perhaps heat or even sound in a big enough
'pile'. I know a prism will produce the heat band but
this was something a bit different.
Townsend Brown referred to the construction of such
piles using lead oxide (I believe) and other materials
in a configuration like battery cells...he figured the
gravity flow through this pile would eventuate to HEAT
which could be used for practical purposes.
I don't find any fault with the idea of using optical
refraction that could lead even to physical vibration
in a big enough 'pile' and with the right
coupling...even melding of one optically refractive
and eventuall other materials to one another.
