Question

In a two-slit setup, each slit is 0.020 mm wide. These apertures are illuminated by plane waves of yellow sodium light (?=589.6 nm). The resulting Fraunhofer fringe pattern consists of 11 narrow bright fringes that gradually decrease in irradiance with distance from the central maximum. Determine the separation between the slits. 10.16* In a two-slit setup, each slit is 0.020 mm wide. These apertures are illuminated by plane waves of yellow sodium light (A The resulting Fraunhofer fringe pattern consists of 11 narrow bright fringes that gradually decrease in irradiance with distance from the cen- tral maximum. Determine the separation between the slits.

Explanation / Answer

by double slit formula, d = lambda*D/y

by single slit formula w = lambda*D/A

                   Also A = (11-1)/2 = 5y

so we have d= 5w = 5*0.020 mm

                      = 0.100 mm Answer
