Bright fringe equation
WebOct 25, 2007 · tan (x)=d/L. a=slit width. x=angle of diffraction (?) m=no. of order. d=distance from the central fringe. L=distance between slit and screen. By using is equation, I found out that the distance between successive dark fringes is increasing as the order increase. Which means that the width of the bright fringes increase with the order. WebThe equations for double slit interference imply that a series of bright and dark lines are formed. For vertical slits, the light spreads out horizontally on either side of the incident beam into a pattern called interference fringes, …

WebJan 5, 2024 · Taking the limit shows that this gives 1: a bright fringe. You can use radians or mm whichever is convenient - they're just connected by trignometry. In figures like the one you show then angles in radians are easy to visualise. If you stick up a screen and look at the fringes it's easiest to measure their visible positions in mm.
