I max =(√ I 1+√ I 2)2 =4 I o

Q. 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 ?

$I_{0}$

$2 I_{0}$

$5 I_{0}$

$4 I_{0}$

$I_{m a x} = (I_{1} + I_{2})^{2}$
$= 4 I_{o}$
