My book tells me that a film as thick as 1 mm does not show interference in daylight. My problem is that m > 5000 before the thickness reaches 1 mm.

Homework Statement A thin film of oil (n = 1.50) floats on water (n = 1.33). If the film appears yellow-green (\lambda = 550 nm) when viewed at normal incidence, how thick is it? Given: n_{f} = 1.50 n_{water} = 1.33 \lambda_{0} = 550 nm \theta_{i} = 0 Required: Thickness (d)...
