Two coherent sources separated by distance d are radiating in phase having wavelength λ. A detector moves in a big circle around the two sources in the plane of the two sources. The angular position of n = 4 interference maxima is given as

(1) sin1nλd

(2) cos14λd

(3) tan1d4λ

(4) cos1λ4d

(2) Here path difference at a point P on the circle is given by

Δx=dcosθ….. (i)

For maxima at P

Δx=nλ….. (ii)

From equation (i) and (ii)
