Does a smaller light speed in a medium rule out the wave theory of light?
The light speed measured by Foucault in water does not fit with a wave theory of light because the light beam is normal to the interface and in this case the incidence angle is zero.
I have seen that abstract theoretical considerations or more complicated experiments previously proposed give headaches to actual theoreticians, therefore this simple cut off experiment suppose only the modification of an angle value. The experiment is at level of actual elementary physics or at level attaint by antique Greeks.
