In the laboratory setting, this is equivalent to the displacement a particle undergoes in between two consecutive frames during imaging with a CCD camera. After a defined number of collisions, the particle is at a new, random location and the distance between its starting location and final location is termed a "displacement". Each collision moves the particle a distance determined by its mean free path setting. This procedure creates a series of displacements generated after a "particle" experiences a series of random molecular collisions.
