Estimating Spatial Coherence Did you use yellow or green for the multimode laser? 1. What did the cross sectional light distribution look like? onne outside 2. Slit spacing where fringes disappear (measured by red-laser): De d y (fringe spacing) 0400307l x (distance to screen)- 152m calculate (on back) d-00003m (estimated spatial coherence) QUESTIONS 1. What is the estimated spatial coherence length of the green or yellow lasers? 2 Based on the cross sectional light distribution of these two lasers does this make sense? Why or why not?
