Problem states: Wavelengths of 690 and 575nm are observed when white light is directed on a film floating in water. The index of the film is 1.25, and the index of water is 1.33.
What is the thichkness?
I know the phase is shifted by pi., but other than that I am not sure where to go with this problem!
Can I get a nudge in the right direction?
Thanks
