    What is the minimum thickness for destructive interference in thin film?

    1. Calculate the minimum thickness of the film for which the intensity of the reflected red ray is near zero. (This is AP Physics B 2010 (c)ii.) I found the wavelength in the film to be 4.81x10-7 m nf=1.382. 2L=mλ (destructive interference) The Attempt at a Solution My first attempt yielded a...
