In YDSE with `d = 1 mm` and `D = 1 m`, Slabs of `(t = 1 mu m, mu = 3)` and `(t = 0.5mu m, mu = 2)` are introduced in front of upper and lower slits, respectively. Find the shift in the fringe pattern.

In YDSE, let A and B be two slits. Films of thickness t_(A) and t_(B) and refractive mu_(A) and mu_(B) are placed in front of A and B, respectively. If mu_(A) t_(A) = mu_(A) t_(B) , then the central maxima will

Figure shows a YDSE setup having identical slits S_(1) and S_(2) with d =5 mm and D = 1 m. A monochromatic light of wavelength lamda = 6000 Å is incident on the plane of slit due to which at screen centre O, an intensity I_(0) is produced with fringe pattern on both sides Now a thin transparent film of 11 mu m thickness and refractive index mu = 2.1 is placed in front of slit S_(1) and now interference patten is observed again on screen. Due to placement of film in front of S_(1) , how many bright fringes cross the point O of screen excluding the one which was at O earlier :

In Young's Double Slit Experiment the distance between the slits and the screen is 1.2 m and the distance between the two slits is 2.4 mm. If a thin transparent mica sheet of thickness 1 mu m and R. I . 1.5 is introduced between one of the interfering beams , the shift in the position of central bright fringer is
