Find fringe width
WebAug 26, 2024 · fring width = difference between maxima =dλD. What is fringe spacing? The fringe spacing or fringe width is the distance between two consecutive bright or dark fringes. In Young’s double-slit experiment all the fringes are of the same length. The fringe width is given by the formula. β = λD/d. What is fringe spacing in double slit experiment? WebThat's how big this would be from here, center point, to the next bright spot is 1.92 meters. That's how you solve this problem. You got to use a little trigonometry. Once you get your angle, you got to relate it to a distance vertically on the screen. This is a common problem using Young's Double Slit.
