This applet demonstrates random walk in two dimensions. The user can specify how many particles appear at the center of the circle and the mean free path as a fraction of the radius of the circle. The path lengths are randomized with an exponential distribution. A histogram shows the number of times each particle has been deflected before it escapes the circle. It also shows the mean number of scatterings and the standard deviation.
This is part of a larger collection of applets by STEM Colorado focused mostly on topics in astronomy. Please note that this resource requires at least version 1.4.2_06 of Java.
