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)"
