Foucault Speed of Light Experiment

  1. Feb 5, 2012 #1
    In my class's set up of Foucault's design of the experiment to measure the speed of light, the light beam passes through a beam splitter but there is only one beam spot in the microscope. I'm confused as to why this is. Can someone help explain it to me?
