Two glass slides are separated by a thin layer of plastic. The glass has an index of refraction nglass and the plastic has an index nplastic. The two indices are not equal. If nplastic = 1.50, for what minimum non-zero thickness of plastic will the transmitted light be for a beam of wavelength 600 nm?
1.400 nm
2.200 nm
3.100 nm
4.One needs to know which of the indices is the greater to solve this.
