A screen is placed 2m away from the 2 points lens to obtain the diffraction pattern in the focal plane of the lens in a single slit diffraction experiment What will be the slit width if the first minimum lies 5 mm on either side of the central maximum when plane light waves of wavelength 4000 are incident on the slit O 0 16 mm O 0 26 mm O 0 36 mm O 0 46 mm
