Figure shows two coherent sources `S_(1)` and `S_(2)` emitting wavelength `lambda`. The separation `S_(1) S_(2) = 1.5 lambda` and `S_(1)` is ahead in phase by `pi // 2` relative to `S_(2)` Then the maxima occur in direction `theta` given by `sin^(-1)` of
(i) 0 (ii) `1// 2` (iii) `-1//6` (iv) `-5 // 6`
Correct option are

Two coherent point sources S_(1) and S_(2) vibrating in phase emit light of wavelength lambda . The separation between the sources is 2lambda . Consider a line passing through S_(2) and perpendicular to line S_(1) S_(2) . Find the position of farthest and nearest minima. .

Figure shows two coherent sources S_(1) and S_(2) which emit sound of wavelength lambda in phase. The separation between the sources is 3lambda. A circular wire of large radius is placed in such a way that S_(1)S_(2) lies in its plane and the middle point of S_(1)S_(2) is at the centre of the wire. Find the angular positions theta, on the wire for which constructive interference takes place.
