Hecht

I'm working on the same problem. Take a look at page 298 in chapter 7 of hecht's optics (I'm assuming you are using Hecht since the problem you asked is identical to 7.12). Anywho, at the bottom of the page in the paragraph is a formula whiich might be useful in getting you started.

You might also take a look at Chapter 9 page 411 at figure 9.22. It's basically the same problem only the film doesn't have an index of refraction.

Anyway, let me know if this was helpful,
