Homework Statement
For the given configuration, the path difference between the 2 rays is given as δ=dsinθ1 - dsinθ2
Homework Equations
Small angle approximation?
The Attempt at a Solution
I'm used to seeing a double-slit situation where only the exit angle is specified, and thus path difference is simply δ=dsinθ. Here, though, we have an incident and refracted θ1 and θ2. Any hints at deriving the following will be appreciated:
δ=dsinθ1 - dsinθ2
