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 :- When a width of one the slits
- of Youngs double slit experiment is double that
of the other than brighter frings are nine times
brighter than the dark fringes.
Reason :- The amplitude of the wave is
proportional to the width of the slit.
