Fizau experiment (on the light speed in moving media : 1851) may be a misunderstanding of the result (Einstein's explanation also). A column made of glass is set horizontally. Two lights (emitted from two light sources) are passing through this glass (from left to right). One light source is approaching toward the glass at high (and uniform) speed. Another is at low (and uniform) speed. The frequency of two incident lights is just the same (thus arranged). Obviously, the frequency of two lights that go out the glass must be the same (if not so, the number of waves that exist in the glass may increase or decrease endlessly). Therefore light speed of two lights in the glass is the same.
