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.

Two coherent source of light can be obtained by

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_(1) and perpendicular to line S_(1) S_(2) . Find the position of farthest and nearest minima. .

A monochromatic point source (S_(1)) is at a distance d from a screen. Another identical source (S_(2)) is at a large distance from the screen. The two sources are on a line which is perpendicular to the screen. Sources are coherent. What is the shape of interference fringes on the screen? (b) Three identical coherent sources are placed on a straight line with two neighbouring ones separated by a distance "d = 0.06 mm" . The sources produce monochromatic light of wavelength lambda" = 550.4 nm" . A line AB is located at a distance D = 2.50 m from the sources and is perpendicular to line joining the three sources. Intensity of light at P with any one of the sources switched on is I_(o) . Find the intensity when all three sources are switched on. Distance of point P from O is "y = 1.72 cm (see figure)"

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 coherent light sources, each of wavelength lambda , are separated by a distance 3 lambda , The maximum number of minima formed on line AB, which funs from -oo to +oo , is

Two microwave coherent point sources emitting waves of wavelenths lambda are placed at 5lambda distance apart.The interference is being observed on a flat non-reflecting surface along a line passing through on sources ,in a direction perpendicular to the line joining the two sources(refer figure) Considering lambda as 4mn ,calculate the positions of maxima and draw shape of interference pattern,takek initial phase differnce between the two sources to be zero.
