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

Two coherent point sources S_1 and S_2 vibrating in phase emit light of wavelength lamda . The separation between them is 2lamda . The light is collected on a screen placed at a distance Dgt gt lamda from the slit S_1 as shown. The minimum distance, so that intensity at P is equal to the intensity at O

Two identical light sources S_1 and S_2 emit light of same wavelength lambda . These light rays will exhibit interference if

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.

Two monochromatic coherent point sources S_(1) and S_(2) are separated by a distance L. Each sources emits light of wavelength lambda , where L gt gt lambda . The line S_(1) S_(2) when extended meets a screen perpendicular to it at point A. Then

The two coherent sources of monochromatic light of wavelength lambda are located at a separation lambda . The two sources are placed on a horizontal line and screen is placed perpendicular to the line joining the sources. Find position of the farthest minima from the centre of the sources.
