Yes,but I think this has to do with permitivity. All of the things you
mention have quite high dielectric constants relative to air,so the
molecules are highly polarizable,and the electron clouds distort when the E
field of the light impinges upon them,and this electron motion opposite to
the impinging field produces the reflected wave in the opposite direction.
Still sorta similar to what happens when the light hits a conductor.

Yeah,that would be a neat thing to see! I'm sure someone has done a decent
simulation of that. The piezo effect is under great study in the fields of
biomechanics and geology.

Hehehe,yeah!
