Reuse & Permissions WebKerr microscopy is based on the magneto-optical Kerr effect, which causes a rotation of linearly polarized light on reflection from a magnetic material . If the linearly polarized … grower and shower meaningA black hole in general is surrounded by a surface, called the event horizon and situated at the Schwarzschild radius for a nonrotating black hole, where the escape velocity is equal to the velocity of light. Within this surface, no observer/particle can maintain itself at a constant radius. It is forced to fall inwards, and so this is sometimes called the static limit. A rotating black hole has the same static limit at its event horizon but there is an additional surfa… grower awards winfield
