please tell me websites about thin films
i could not find any useful site about thin films. please tell me about websites including information of thin films and their optical properties as well.
Homework Statement
Calculate the minimum thickness of a layer of manesium flouride(n=1.38) on flint glass (n=1.66) in a lens system, if light wavelength 5.50x10^2 nm in air undergoes destructive interference.
Given:
n1=1.38
n2=1.66
λ1=5.5*10^2 nm
Homework Equations
Δx=L(λ/2t)...
I basically understand the idea of the changes in phases of interference in thin films but i was hoping for a better explanation. i understand that the thickness of the lens effects the the exit phase but i don't know why PLEASE HELP! Thank you
A thin film of oil (n = 1.10) is located on a smooth, wet pavement. When viewed perpendicular to the pavement, the film appears to be predominantly red (640 nm) and has no component of wavelength 569 nm. How thick is the oil film?
I have tried using 2nt=(m+1/2)wavelength but am having...
This is not a textbook question. It is strictly some concepts which I am confused about.
Suppose we have thin film situation.

I'm really stuck on this question:
A soap film is 100 nm thick. What wavelength of light will be most strongly reflected by this film; that is, what colour will it appear? (n soap = 1.33).
Any help you could provide would be greatly appreciated.
