The light waves from


The light waves from two coherent sources have same intensity $\mathrm{I}_{1}=\mathrm{I}_{2}=\mathrm{I}_{0}$. In interference pattern the intensity of light at minima is zero. What will be the intensity of light at maxima ?

  1. $\mathrm{I}_{0}$

  2. $2 \mathrm{I}_{0}$

  3. $5 \mathrm{I}_{0}$

  4. $4 \mathrm{I}_{0}$

Correct Option: , 4


$\mathrm{I}_{\max }=\left(\sqrt{\mathrm{I}_{1}}+\sqrt{\mathrm{I}_{2}}\right)^{2}$

$=4 \mathrm{I}_{0}$
