We have investigated multiple gravitational lensing by numerical “ray tracing” simulations. We have found that the distance between rays grows exponentially, on average, until it reaches the projected mean separation of lensing objects (∼ RV–1/2, where R is the system size and N is the number of scattering object). This nature may affect observations of high redshift objects or the anisotropy of the cosmic background radiation.
