Minimum Thickness Of Plastic What Is The Minimum Plastic Film Thickness Required For Constructive Interference?

What is the minimum plastic film thickness required for constructive interference? - minimum thickness of plastic

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?

u0026lt of 1 \\ \\ \\ \\ \\ \\ \\ \\, 1.3 \\ \\ \\ \\ \\ \\ \\ \\ u0026lt, 1.5, 180deg phase difference condition. To reverse the condition of constructive interference and destructive interference.
The minimum thickness will be measured by the formula

t = λ/2n
t = 211.53nm
