Optical Physics - Interference, Diffraction and Polarization of waves Please highlight the formula that are needed and write solutions neatly and completely. For study purposes.

A light of wavelength at 700nm falls almost perpendicularly on a thin film with index of refraction n₂.
Below the film is an infinitely thick layer with index of refraction n3
a. If n₁=1.5, n₂=1.8 and n3 = 2.5.
What is the minimum non-zero film thickness to get destructive interference?
b. If n₁1.5, n₂=1.8, n3 = 2.5.
What is the minimum non-zero film thickness to get constructive interference?
If n₁= 1.8, n₂=1.5 and n3 = 2.5.
What is the minimum non-zero film thickness to get destructive interference?
d. If n₁1.8, n₂=1.5 and n3 = 2.5.
What is the minimum non-zero film thickness to get constructive interference?
C.
