A coherent light is incident on two paralle slits `S_(1) and S_(2)`. At a point `P_(1)` the frings will be dark if the phase difference between the rays coming from `S_(1) and S_(2)` is

A

`n pi ` radians

B

`(n+0.5) pi` radians

C

`(2n+0.5) pi` radians

D

(`2n+1) pi` radians

Text Solution

Verified by Experts

The correct Answer is:
D
Fow destructive interference, phase difference should be odd multiple of `pi`.

Coherent light is incident on two fine parallel slits S_(1) and S_(2) as show in fig. If a dark fringe occurs at P, which of the following gives possible phase difference for the light waves arriving at P from S_(1) and S_(2) ?

Three coherent sources S_(1), S_(2)" and" S_(3) can throw light on a screen. With S_(1) switched on intensity at a point P on the screen was observed to be I. With only S_(2) on, intensity at P was 2I and when all three are switched on the intensity at P becomes zero. Intensity at P is I when S_(1)" and" S_(2) are kept on. Find the phase difference between the waves reaching at P from sources S_(1) "and" S_(3) .

In a modified Young's double-slit experiment, source S is kept in front of slit S_(1) as shown in the following figure. Find the phase difference at a point that is equidistant from slits S_(1) and S_(2) and point P that is in front of slit S_(1) in the following situations: If a liquid of refractive index n is filled between the screen and slits, what is the phase difference?

Among two interfering sources, let S_1 be ahead of the phase by 90^@ relative to S_2 . If an observation point P is such that PS_1 - PS_2 = 1.5 lambda , the phase difference between the waves from S_1 and S_2 reaching P is

Parallel monochromatic beam is falling normally on two slits S_(1) and S_(2) separated by d as shown in figure. By some mechanism, the separation between the slits S_(3) and S_(4) can be changed. The intensity is measured at the point P which is at the common perpendicular bisector of S_(1)S_(2) and S_(3)S_(4) . When z=(Dlambda)/(2d) , the intensity measured at P is I. and when z is equal to (4Dlambda)/(d) , Intensity is x l. Find x.
