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 two coherent waves of intensity \( I_{1} \) and \( I_{2} \) are superimposed with a constant phase different \( \phi \), then the intensity of resultant wave is given by \( I=I_{1}+I_{2}+2 \sqrt{I_{1} I_{2}} \cos \phi \)

Reason : For two incoherent sources, resultant intensity is given by \( \mathrm{I}=\mathrm{I}_{1}+\mathrm{I}_{2} \).
(1) \( \mathrm{A} \)
(2) B
(3) \( \mathrm{C} \)
