Consider the situation shown in figure , The two slits S_(1) and S_(2) placedsymmetrically aroundthe central line are illumated by a monocharmoticby a monocharomatic light of wavelength lambda . The separation betweenthe slits is d . The light transmittedby the slits falls on a screen Sigma_(1) placedat a distanceD from theslits . The slitS_(3)is at the central lineandthe slit S_(4)is at a distance z from S_(3) .Another screen Sigma_(2)is placed a further distance D away from Sigma_(1).Find the ratio of the minimum intensity observed on Sigma_(2) if z is equalto (1) z = (lambdaD)/(2d) (2) (lambdaD)/d (3) (lambdaD)/(4d) |
