Refraction Problem #1 Goal: Find the distance the light ray displaced due to the thick window and how much time it spends in the glass. Some hints are given. 20° O 1. Find 6, (just for fun). 20° H,0 2. To show incoming & outgoing rays are parallel, find 0. 20° n, = 1.3 3. Find d. 0.504 m | 10m glass 4. Find the time the light spends in the glass. n2 = 1.5 5.2 10-8 s Extra practice: Find 0 if bottom medium is replaced with air. H,0
