Path Difference in Wave Optics Formulas

Path Difference is the difference in distance traveled by two waves, which determines the phase shift between them, affecting the resulting interference pattern. And is denoted by Δx. Path Difference is usually measured using the Centimeter for Length. Note that the value of Path Difference is always negative.
