(5 points) in the picture above, if n1 < n2 indicate which side of the wave front is traveling faster, the side of the wave front in medium 1 or in medium 2? (5 points) just as a turning car turns toward the slow-moving side, does the light turn toward or away from the surface normal as it passes from medium 1 to medium 2? draw the direction of the refracted ray (the direction of travel in medium 2) in the picture. (5 points) is there an incident angle such that there is no refracted light in this case? explain.
