GR Schwarzschild Light Launch Angle Program
written by Wolfgang Christian, Mario Belloni, and Anne Cox
educational validator: Bethany Zach
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.
Please note that this resource requires at least version 1.5 of Java.
