1.	Consider the situation shown in figure (17-E6). The two slits S1 and S2 placed symmetrically around the central line are illuminated by a monochromatic light of wavelength λ the separation between the slits is d. The light transmitted by the slits falls on a screen ∑1 placed at a distance D from the slits. The slitS3 is at the central line and the slit S4 is at a distane z rom S3 Another screen ∑2 is palced a further distance D away from ∑1 find the ration of thmaximum to minimum intensity obsered on ∑2 if z is equal to (a) z=λD2d (b) λd, (c) λD4d.
Answer» Consider the situation shown in figure (17-E6). The two slits $S_{1}$ and $S_{2}$ placed symmetrically around the central line are illuminated by a monochromatic light of wavelength $λ$ the separation between the slits is d. The light transmitted by the slits falls on a screen $\sum_{1}$ placed at a distance D from the slits. The slit $S_{3}$ is at the central line and the slit $S_{4}$ is at a distane z rom $S_{3}$ Another screen $\sum_{2}$ is palced a further distance D away from $\sum_{1}$ find the ration of thmaximum to minimum intensity obsered on $\sum_{2}$ if z is equal to (a) $z = \frac{λ D}{2 d}$ (b) $\frac{λ}{d},$ (c) $\frac{λ D}{4 d} .$

Consider the situation shown in figure (17-E6). The two slits $S_{1}$ and $S_{2}$ placed symmetrically around the central line are illuminated by a monochromatic light of wavelength $λ$ the separation between the slits is d. The light transmitted by the slits falls on a screen $\sum_{1}$ placed at a distance D from the slits. The slit $S_{3}$ is at the central line and the slit $S_{4}$ is at a distane z rom $S_{3}$ Another screen $\sum_{2}$ is palced a further distance D away from $\sum_{1}$ find the ration of thmaximum to minimum intensity obsered on $\sum_{2}$ if z is equal to
(a) $z = \frac{λ D}{2 d}$
(b) $\frac{λ}{d},$
(c) $\frac{λ D}{4 d} .$
