On placing a thin film of mica of thickness `12xx10^(-5)cm` in the path of one of the interfering beams in young's double slit experiment using monochromatic light, the fringe pattern shifts through a distance equal to the width of a bright fringe. If `lamda=6xx10^(-5)cm`, the refractive index of mica is

On introducing a thin sheet of mica (thickness 12 xx 10^(-7) cm) in path of one of the interfering beams ( lambda_("vacuum") = 600 nm ) in Young's double-slit experiment, the central fringe is shifted through a distance equal to the spacing between successive bright fringes. Calculate the refractive index of mica.

When a thin sheet of a transparent material of thinkness 7.2xx10^(-4) cm is introduced in the path one of the interfering beams, the central fringe shift to a position occupied by the sixth bright fringe. If lambda=6xx10^(-5) cm, find the refractive index of the sheet.

A glass sheet 12xx10^(-3) mm thick (mu_(g)=1.5) is placed in the path of one of the interfering beams in a Yongs's double slit interference arrangement using monochromatic light of wavelenght 6000 A.

In young double slit experiment, if the width of 4^(th) bright fringe is 2 times 10^-2 cm , then the width of 6^(th) bright fringe will be….cm.

A thin sheet of glass (refractive index 1.5) of thickness 6 microns, introduced in the path of one of the interfering beams in a double-slit experiment shift the central fringe to a position earlier occupied by the fifth bright fringe. The wavelength of light used is

Monochromatic light of wavelength 6000Å was used to set up interference fringes. On the pasth of the interhering waves a mica sheet 12xx10^(-5) cm thick was placed when the central bright fringe was found to be displaced by a distance equal to the width of a bright fringe. what is the refractive index of mica?
