368119 Two monochromatic coherent point sources S1andS2 are separated by a distance L . Each source emits light of wavelength λ, where L>>λ. The lines S1S2 when extended meets a screen perpendicular to it at a point A.

1 The interference fringes on the screen are straight lines perpendicular to the line S1S2A
2 The interference fringes on the screen are circular in shape
3 The point A is always bright for any separation L
4 The point is bright if L=nλ/2

368122 Assertion :
Two point coherent sources of light S1, and S2 are placed on a line as shown. P and Q are two points on that line. If at point P maximum intensity is observed then maximum intensity should also be observed at Q.

Reason :
In the figure of assertion if the distance |S1PS2P| is equal to distance |S2QS1Q| then maximum intensity is observed at both P and Q.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Assertion is incorrect but reason is correct.
