goldfish scales



In my mis-spent youth, I recall an assigned problem in thin-film
interference, in which the thicknesses and indices of refraction for several
layers in a fish scale were given, and the question asked was "What color is
the fish?"

We'd like to work it through as an in-class exercise, but can't seem to
locate the data. Does anybody have the appropriate data, or a notion where
we might find it?

Thanks!
