Homework Statement
A thin film of oil (n = 1.50) is spread over a puddle of water (n = 1.33). In a region where the film looks red from directly above (λ = 626 nm), what is the minimum possible thickness of the film?
Homework Equations
2nt = (m+0.5)λ
t = (m+0.5)λ/2n
The Attempt at a Solution
t = (1+0.5)(626E-9m)/2(1.50)
t = 313 nm
Anyone please correct the solution.
