Homework Statement
What is the minimum (non-zero) thickness of a benzene (n = 1.501) thin film that will result in constructive interference when viewed at normal incidence and illuminated with orange light (lamba = 615 nm)? A glass slide (ng = 1.620) supports the thin film
answer= 204 nm
Homework Equations
I rearranged an equation to get
t= (m=.5)(lambda) / 2*n
but I'm thrown off by how they give me two n values?
The Attempt at a Solution
I tried using my equation plugging in each n, but did not get the answer.
please help, thanks in advance :)
