A. If both Assertion \& Reason are True \& the Reason is a correct explanation of the Assertion.
B. If both Assertion \& Reason are True but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion \& Reason are False.
Assertion :- In a YDSE, the two slits are at distance a apart. Interference pattern is observed on a screen at a distance D from the slits. At a point on the screen which is directly opposite to the slit, a dark fringe is observed. Then the wavelength of wave is proportional - to square of distance between slits.
Reason :- The light ray coming from two slits do not interfere at the screen.
