A. If both Assertion \& Reason are True \& the Reason is a correct explanation of the Assertion.
\( \mathrm{P} \)
B. If both Assertion \& Reason are True but Reason is not a
W correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion \& Reason are False.
Assertion :- In single slit diffraction arrangement, instead of keeping the screen far away, often a converging lens is placed after the slit and a screen is placed at its focus.
Reason :- Lens doesn't introduce any extra path difference for a parallel beam.
