If the plane wave is split & recombined on a screen after the two portions, which are polarized in the x & y directions, have travelled an optical path difference of  {\dfrac{2 \pi}{k}} , the observed average intensity will be proportional to :

Select one:
{E_{1}^{2} - E_{2}^{2}}
{\left (E_{1} + E_{2} \right )^2} Incorrect
{E_{1}^{2} + E_{2}^{2}}
{\left (E_{1} - E_{2} \right )^2}
the correct answer is a)
can some one explain how?
