Fnet = sum of all force
horizontal net force = Ff + Fa
Answer
given,
thickness of the oil film = 234 n m
refractive index of oil = n = 1.65
Visible light (in air) has wavelengths between 430 nm (blue) and 770 nm (red)
λ = ?
condition of constructive interference
2 n t + λ/2 = k λ
now,
at k = 1
not between the visible range
at k =2
above wavelength is in the visible range.
That's the answer: I've attached the pic
