These are the vertical distances (measured as a time) to the origin and destination. As you moved the green dot, a graph of total flight time was produced, a value is also provided near the bottom of simulation. Move the green dot to where the graph is a minimum. Verify the location by watching the total time at the bottom. Once at this minimum, record the time in medium 1 (RIG time) and the time in medium 2 (GtP time) flight times. These are the distances from the origin to the refraction location and from the refraction location to the destination. ( NOTE: we are measuring a time here, not a distance, as you would expect. However if we were to convert our time to a distance, both the vertical (VGtP) and hypotenuse (GtP) distances would change by the same amount, keeping the angle the same as that for our measures in time). RtG time = 13.45 ns GtP time = 21. 9le nis Determine the incident angle (as measured from the normal) using Oinc = cos"(VRtG / RtG) Determine the refracted angle (as measured from the normal) using Orefracted = cos (VGtP / GtP) Oinc = Orefracted = Calculate nj sin (Oinc) and nj sin (Orefracted). How do these compare? Calculate the percent difference of these two terms
