The light waves from two coherent sources have same intensity $I_1 = I_2 = I_0$. In interference pattern the intensity of light at minima is zero. What will be the intensity of light at maxima?
Answer: (C) $4I_0$
$I_{max} = \left(\sqrt{I_1} + \sqrt{I_2}\right)^2 = \left(2\sqrt{I_0}\right)^2 = 4I_0$.
