Analyze light path around a black hole with this tool. GR Schwarzschild Light program simulates the path of light around a black hole using the Schwarzschild metric. It also displays a plot of the effective potential of light in the vicinity of a black hole. The default setting is a light trajectory that escapes the black hole.

GR Schwarzschild Light is part of a suite of Open Source Physics programs that model aspects of General Relativity. It is distributed as a ready-to-run (compiled) Java archive. Double clicking the gr_schwarzschild_light.jar file will run the program if Java is installed. Other programs provide additional visualizations. They can be found by searching ComPADRE for Open Source Physics, OSP, or General Relativity.
