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

Two coherent sources S_1 and S_2 area separated by a distance four times the wavelength lambda of the source. The sources lie along y axis whereas a detector moves along +x axis. Leaving the origin and far off points the number of points where maxima are observed is

Assertion: Two coherent sources S_1 and S_2 are placed in front of a screen as shown in figure. At point P, 10th order maxima is obtained. Then , 11th order maxima will be obtained above P. Reason: For 11th order maxima path difference should be more.

Consider two coherent, monochromatic (wavelength lambda ) sources S_(1) and S_(2) , separated by a distance d. The ratio of intensities of S_(1) and that of S_(2) (which is responsible for interference at point P, where detector is located) is 4. The distance of point P from S_(1) is (if the resultant intensity at point P is equal to (9)/(4) times of intensity of S_(1) ) ("Given : "angleS_(2)S_(1)P=90^(@), d gt0 and n" is a positive integer")

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

Three coherent point sources S_(1),S_(2) and S_(3) are placed on a line perpendicular to the screen as shown in the figure. The wavelength of the light emitted by the sources is lambda. The distance between adjacent sources is d=3lambda The distance of S_(2) from the screen is D (gtgt lambda) . Find the minimum (non zero) distance x of a point P on the screen at which complete darkness is obtained.

Two coherent monochromatic point sources S_1 and S_2 are placed in front of an infinite screen as shown in figure. Wavelength of the light emitted by both the sources is zero. Initial phase difference between the sources is zero. Initially S_(1)S_(2)=2.5 lambda and the number of bright circular rings on the screen in n_(1) . if the distance S_(1)S_(2) is increased and made 5.7 lambda , the number of bright circular rings becomes n_(2) . the difference n_(2)-n_(1) is

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. .
