Question
What is the relation between phase difference and Optical path in terms of speed of light in a vacuum?
✓
Answer
Phase difference, $\Delta \Phi^{\prime}=\frac{\omega}{c} \times n \Delta x$ where ω is the angular frequency, c is the speed of light in vacuum and nΔx is an optical path for a wave travelling in the medium of refractive index n.
