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 :- If in YDSE \( \frac{d}{\lambda}=200 \) and screen is
semicylinderical as shown. Axis of semicylinder is passing through mid point between slits.
then number of bright fringes are 200.
Reason :- Maximum path difference is \( \mathrm{n} \lambda=\mathrm{d} \) between lowest and highest position and \( \mathrm{n}=\frac{\mathrm{d}}{\lambda}=200 \).
(1) A
(2) B
(3) \( \mathrm{C} \)
