Mar 12, 2014 at 15:40 comment added YungHummmma @dmckee Also, a question related to that: You need the full spectrum of frequencies to create arbitrary functions. So what happens if you shine monochromatic light on it?
Mar 12, 2014 at 15:24 comment added YungHummmma @dmckee Right, so that was my first thought in response: plane waves form a complete set, so anything else is just some linear combination of them. What do you mean by 'locally' though? Just within the film?
Mar 12, 2014 at 15:14 comment added dmckee --- ex-moderator kitten It is true that any arrangement of fields can be locally modeled as a sum over plane waves, so the question reduces to either "Am I satisfied with local correctness?" or "Is the plane wave description correct over a sufficiently extended area in this case?" depending on your problem.
