We examine the effect of a Gaussian wave pulse, propagating along a cosmic string, on both the observed position and redshift of the double images of an object behind the string. We also calculate the effect of the string on a rectangular grid of stars which are located infinitely far behind the string. The calculations are done numerically using the exact metric for a traveling wave recently discovered by Garfinkle.
