In a single slit diffraction pattern , consider the wavelength is λ and the pointon the screen is 70 away from the central maximum. If the total phase differencebetween wavelets from the top and bottom of the slit is 66 rad, then the width ofthe slit
let l be the wavelength of light wavepi=3.14phase difference =2pi/l *path differencewhere path difference is dx/Dhere d is the slit separationand D is the distance between slit plane and screenAs u did not mention the units correctly I m not giving numerical answer
