Question

Monochromatic light waves of intensities $l_1$ and $l_2$ and a constant phase difference $\varphi$ produce an interference pattern. State an expression for the resultant intensity at a point in the pattern. Hence deduce the expressions for the resultant intensity, maximum intensity and minimum intensity if $I _1= I _2= I _0$
