Optics in a field of gravity
arXiv:0812.2816 · doi:10.1119/1.3099560
Abstract
An observer at rest in a uniformly accelerated reference frame experiences a parallel gravitational field, where the rays of light are formed as circular arcs instead of being straight lines. We deduce how a sphere at rest in the Rindler frame, and a freely falling sphere, will appear to an observer at rest in the frame.
