$I_0$/2
2/$I_0$
2$I_0$
$I_0$/√2
Hide Solution
Verified By Collegedunia
The Correct Option is
C
Solution and Explanation
The correct answer is (C): 2$I_0$
As we know the phase difference is varying, then the waves are said to be incoherent. So, the intensity of resultant wave is the sum of intensities of each wave is 2$I_0$.
