Explanation / Answer
. 1. Snell’sLaw: [sin(1) /sin(2)] = (n2) / (n1) =(v1) / (v2) 2. For the first question, Snell's law tells usthat the two materials have matching indexes of refraction. Having matching indexes of refraction does not mean that the twomaterials are identical. Therefore, only the first box ischecked for the first question. . 3. For the second question, we know from Snell'slaw that light bends at the interface towards the more dense orhigher index of refraction. Since the light is fartherfrom the normal, it is bending away from the normal which means thesecond material has a lower index of refraction than the firstmaterial. We also know from Snell's law that the indexes ofrefraction is inversely proportional to the velocity withinthe material; that means that when passing to a less dense materialthe velocity must increase. Therefore, the second box and thethird box are checked for the second question. . 2. For the first question, Snell's law tells usthat the two materials have matching indexes of refraction.
