1. The problem statement, all variables and given/known data When light is shined on thin films the interference pattern results in: a. there is no interference pattern *b. rainbow like colors c. light and dark pattern with no separation of colors d. a mirror quality reflection e. polarization of the light 3. The attempt at a solution I thought the answer was c because I thought all interference was seen this way but the answer key says the answer is b. Can someone explain why? Thanks!
