The GR Schwarzschild Light Launch Angle program simulates the path of light around a black hole using the Schwarzschild metric and allows the user to set the launch angle of the light. It also displays a plot of the effective potential well for the light. The default setting is light with an r-coordinate value of 3.5 and a launch angle of 1.571 (in radians).
GR Schwarzschild Light Launch Angle Parameter 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_launch_angle.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.
