Follow these steps to solve this problem: A very thin oil film (noil - 1.25) floats on water (nwater = 1.33). What is the thinnest film that produces a strong reflection for green light with a wavelength of 500 nm? Part A As light travels from air into the water through the oil film, View Available Hint(s) both of the reflected waves undergo a phase change. neither of the reflected waves undergoes a phase change only one of the reflected waves undergoes a phase change.

There is a phase change everytime there is a change in the refractive index and when it increases. So both the reflected waves undergo phase change. Option no. 1 is the answer.
t= mair/2nfilm
For the thinnest film, m=1.
t= 50010-9/2
1.25
t= 210-7m.
