A monochromatic light source of wavelength x is placed at S. Three slits S1, S2and S3 are equidistant from the source S and the point P on the screen.S1P - S2P = x/6 and S1P - S3P = 2x/3. If I be the intensity at P when only one slit is open. What is the intensity at P when all the three slits are open?

In my opinion answer should be 1I as phase diff between s2 and s3 is pi. Hence only intensity will be by slit s1 which is I.
