Homework Equations
The Attempt at a Solution
Not too sure how to do this one.
I tried thinking about what it was doing before the air was replaced with the liquid.
With air,
The first reflection would have no phase shift (glass index to air index), the second reflection would have a phase shift of pi (air index to glass index) so overall we a have a phase shift of pi.
How do I obtain an expression about the interference pattern from this?
With the liquid instead of the air, we will still have a phase change of pi but the wavelength will change since the index of the liquid is 4/3 not 1.
Any ideas?
Thanks again!
