What is the minimum plastic film thickness required for constructive interference? - plastic thickness mil
A thin plastic film with a refractive index increase of 1.3 on the surface of the car window (n = 1.5) in a position to the reflectivity of the window. What is the minimum thickness of the film is necessary if the light of wavelength 550 nm in the air from both sides of the film reflected and interfere constructively?

The minimum thickness will be measured by the formula
t = λ/2n
t = 211.53nm
