How to Calculate Path difference in Young's double-slit experiment?
Path difference in Young's double-slit experiment calculator uses Path Difference = sqrt((Distance from center to the light source+(Distance between two coherent sources/2))^2+(Distance between slits and screen)^2)-sqrt((Distance from center to the light source-(Distance between two coherent sources/2))^2+(Distance between slits and screen)^2) to calculate the Path Difference, Path difference in Young's double-slit experiment is because the wave reaching light source from the second coherent source must travel a longer path than the wave reaching light source from the first coherent source. Path Difference is denoted by k symbol.
How to calculate Path difference in Young's double-slit experiment using this online calculator? To use this online calculator for Path difference in Young's double-slit experiment, enter Distance from center to the light source (y), Distance between two coherent sources (d) & Distance between slits and screen (D) and hit the calculate button. Here is how the Path difference in Young's double-slit experiment calculation can be explained with given input values -> 0.009659 = sqrt((0.02+(0.1/2))^2+(0.2)^2)-sqrt((0.02-(0.1/2))^2+(0.2)^2).
