Two coherent point source S_(1) and S_(2) vibrating in phase emit light of wavelength lambda . The separation between them is 2 lambda as shown in figure. The first bright fringe is formed at 'P' due to interference on a screen placed at distance 'D' from S_(1)(Dgtgtlambda) , then OP is 1) sqrt(3)D , 2) 1.5D , 3) sqrt(2)D , 4) 2D

The figure shows two points source which emit light of wavelength lambda in phase with each other and are at a distance d = 5.5 lambda apart along a line which is perpendicular to a large screen at a distance L from the centre of the source. Assume that d is much less than L. Which of the following statement is (are) correct ?
