Summary[edit]
DescriptionBlack Hole Shadow.gif |
English: A plane wave of light passes by a static black hole and some of the light-rays are absorbed. The ones absorbed are those that have an impact parameter less than the radius . By the reversibility of light, this means that looking at this sphere is equivalent to looking at the surface of the event horizon. This lensing effect causes the apparent size of the black hole to be bigger, by a factor of about . The photon sphere is also depicted, as the region where orbiting light-rays going in are inevitably absorbed, and orbiting rays going out can escape. |
