In a thin film of oil on water, if the thickness of the film is 500 nm, what is the condition for destructive interference for light of wavelength 600 nm in air?
2t = (m + 1/2)λ
2t = mλ
t = (m + 1/2)λ
t = mλ/2
For destructive interference in a thin film, the condition is 2t = (m + 1/2)λ, where m is an integer.
