Conceptual Questions: 1) There is no index of refraction less than one because nothing is as transparent as air. 2) The frequency does not change but since (Frequency = velocity/wavelength), both the velocity and wavelength will change in a way that the frequency will not. Analysis: In activity 1, we were to use Snell’s law to find index of refraction of an acrylic cube. To do this we placed an acrylic cube on the upper left-hand corner of paper. Outlined the cube and labeled the corners A,B,C,and D. Then labeled every cm on the bottom side and marked G1-4. Then looked through the cube from each G point until we lined up A and labeled those points E1-4 and traced lines to their corresponding G point. Also traced lines from point A to each G point and from there to points P1-4. From all these points we found the average index of refraction to be 1.31. In activity 2, we used the computer to simulate a concave mirror and found the distance to the image and the size of the image for different object distances.
