Homework Statement
A thin layer of water (n=1.33) is surrounded by air what wavelength of light will not be transmitted through the water at the point where the water is 113 nm thick?
The Attempt at a Solution
- In phase
- Path difference of 2T.
- Constructive Interference
I just don't know how to set up the formula to find the wavelength. I know to find the wavelength in water I divide wavelenght in air by the index of refraction of water.
Any help appreciated, cheers.
