As a follow up to my last animation on the emission theory here is a short animation of the Michelson Morely experiment using the wave theory. Notice that this theory predicts a fringe shift because the wave front on the vertical leg comes back to corner before the wave front on the horizontal leg. https://drive.google.com/file/d/1Iw9UDpZx133Hmb4oWzI9oO_C1-ebQAWn/view?usp=sharing
