What would be the resultant intensity at a point of constructive interference, if there are two identical coherent waves of intensity I’ producing an interference pattern?

What would be the resultant intensity at a point of constructive interference, if there are two identical coherent waves of intensity I’ producing an interference pattern? Correct Answer 4 I’

Resultant intensity at the point of constructive interference is given as follows: I = I’ + I’ + 2√I’I’ cos 0o I = 4 I‘ Therefore, the value of the resultant intensity at a point of constructive interference is 4 I’.
