Light of wavelength 500nm is used to form interference pattern in Young's double slit experiment. A uniform glass plate of refractive index 1.5 and thickness 0.1mm is introduced in the path of one of the interfering beams. The number of fringes which will shift the cross wire due to this is

In Young's experiment if mica disc of thickness t and refractive index is placed in the path of one ray coming out of slit, fringes will move ...... distance on the screen

In double slite experiment if the transparent material of refractive index mu s introduced in between second slit and screen, the fringe widht on the screen moves

In Young's double slit experiment a mica plate of refractive index mu is introduced in the path of light coming from one of the slit . If the central bright fringe gets shifted to the point originally occupied by the fourth bright fringe, then the thickness of the mica plate will be (symbols have their usual meaning )
