A thin layer of oil (n = 1.50) floats on water (n = 1.33). Destructive interference is observed for light of wavelength 470 nm. Find the minimum non-zero thickness of the oil film assuming normal incidence.
4) Blue light (440 nm) shines on water (n-1.33) that has a thin layer of oil (n=1.10) floating on it. What is the minimum thickness of oil that produces constructive interference for this light
Thin Film Interference Problems 1. Oil (n=1.25) floats on water. What is the minimum thickness of oil in a region where it appears green ( = 525 nm)? (Ans: 210 nm) 2. A 500 nm thick layer of oil (n = 1.25) floats on water. What wavelengths of light in the visible range (400 nm to 700 nm) are maximally reflected? (Ans: 417 nm, 625 nm) 3. Athin film of acetone (n = 1.25) coats a thick glass plate (n...

A light ray in air (n= 1) is incident on a thin film of oil (noil = 1.60) floating on top of water (nwater = 1.33), as shown below. The wavelength of the incident light in air is Aair = 640 nm. The oil layer has a thickness t = 0.5 um. The ray is assumed to be incident practically along the normal. That is, we won't be worried about angles of reflection or refraction when doing this problem. However,...
