Two coherent sources separated by distance d are radiating in phase having wavelength A detector moves in a big circle around the two sources in the plane of the two sources. The angular position of interference maxima is given as:
Path difference at a point Q on the circle is
(i)
For maxima at Q path difference should be integer multiple of wavelength
(ii)
From eqs. (i) and (ii),
For
Angular position,
