A monochromatic beam of light fall on YDSE apparatus at some angle (say `theta`) as shown in figure. A thin sheet of glass is inserted in front of the lower slit `s_(2)`. The central bright fringe (path difference `= 0`) will be obtained

A monochromatic beam of light falls on YDSE apparatus at some angle (theta) as shown, a thin sheet of glas (R.I. = mu , thickness = t) is insdted in front of the lower slit S_(2) . Select the correct alternative.

A monochromatic beam of light falls on Young's double slit experiment apparatus as shown in figure. A thin sheet of glass is inserted in front of lower slit S_(2) (lambda = 600 nm is wavelength of source) If central bright fringe is obtained on screen at 'O' then

A vessel ABCD of 10 cm width has two small slits S_(1) and S_(2) sealed with idebtical glass plates of equal thickness. The distance between the slits is 0.8 mm . POQ is the line perpendicular to the plane AB and passing through O, the middle point of S_(1) and S_(2) . A monochromatic light source is kept at S, 40 cm below P and 2 m from the vessel, to illuminate the slits as shown in the figure. Calculate the position of the central bright fringe on the other wall CD with respect of the line OQ . Now, a liquid is poured into the vessel and filled up to OQ . The central bright fringe is fiund to be at Q. Calculate the refractive index of the liquid.

Assertion In the YDSE set up shown in figure a glass slab is inserted in front of the slit S_(1) as shown in figure Then zero order maxima (where path difference =0) will lie above point O. Reason Glass slab will produce an extra path difference in the path of the ray passing through S_(1)
