A coherent light is incident on two paralle slits S_(1) and S_(2) . At a point P_(1) the frings will be dark if the phase difference between the rays coming from S_(1) and S_(2) is

Monochromatic light of wavelength lamda passes through a very narrow slit S and then strikes a screen placed at a distance D = 1m in which there are two parallel slits S_(1) and S_(2) as shown. Slit S_(1) is directly in line with S while S_(2) is displaced a distance d to one side. The light is detected at point P on a second screen, equidistant from S_(1) and S_(2) When either slit S_(1) or S_(2) is open equal light intensities I are measured at point P. When both slits are open, the intensity is three times as large i.e. 3 I . If the minimum possible wavelength is Nd^(2) , then find the value of N (d lt lt D)

In the set up shown in figure, the two slits S_1 and S_2 are not equidistant from the slit S. The central fringe at O is then

Three coherent sources S_(1), S_(2)" and" S_(3) can throw light on a screen. With S_(1) switched on intensity at a point P on the screen was observed to be I. With only S_(2) on, intensity at P was 2I and when all three are switched on the intensity at P becomes zero. Intensity at P is I when S_(1)" and" S_(2) are kept on. Find the phase difference between the waves reaching at P from sources S_(1) "and" S_(3) .

In an interference experiment, the two slits S_(1) and S_(2) are not equidistant from the source S. then the central fringe at 0 will be

Find the phase difference at a point that is equidistant from slits S_(1) and S_(2) and point P that is in front of slit S_(1) in the following situations: If a liquid of refractive index n is filled between the screen and slits, what is the phase difference?
