comment Home experiments to derive the speed of light?
I think so - light travels about 1 foot per 1.02 nanoseconds, so you're bumping against the accuracy of the cheapest O-scopes, but my little $200 USB Oscope will do 50 ns/division. I think you should still be able to do it by making one light path very short and the other very long, then adjust your math accordingly. Then you could see the difference of half a division or so...
