DimaMazin Posted December 29, 2013 Author Share Posted December 29, 2013 What is a variable deflective index? Can we define deflection angle on short part of photon path in gravitational field? Link to comment Share on other sites More sharing options...

DimaMazin Posted January 3, 2014 Author Share Posted January 3, 2014 See post #6. I think deflection angle of photon approaching(under some angle) to mass on short part of the photon path = rs/r2 - rs/r1 Can we define the travel time of photon on the part of photon path in seconds of far observer? -1 Link to comment Share on other sites More sharing options...
