Given, length of the sheet, `t=10` cm
refractive index, `mu=1.4`
:. Optical path `=mut=(1.4)xx(10)=14 cm`

In young,s double slit experience monochromatic light, the frings pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.6 and thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then sheet is then removed and the distance between the slits and the screen is doubled. It is found that now the distance between succesive maximum (or minimum) is the same as the observed fringe-shift upon the introduction o fthe mica sheet. Calculate the wavelength of the monochromatic light used in the experiment.

In YDSE using monochromatic light the fringe pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.6 and thickness 1.964 microns is introduced in the path of one of the interfering waves. The mica sheet is then removed and the distance between the plane of slits and the screen is doubled. It is found that the distance between successive maxima (or minima) now is the same as the observed fringe shift upon the introduction of the mica sheet. Calculate the wavelength of the light.

In YDSE using monochromatic light, the fringe pattern shifts by a certain distance on the screen when a mica sheet of refractive index 1.5 and thickness 2 microns is introduced in the path of one of the interfering waves. The mica sheet is then removed and the distance between the plane of slits and the screen is doubled. It is found that the distance between successive maxima (or minima) now is the same as the observed fringe shift upon the introduction of the mica sheet. Calculate the wavelength of the light.

In Fresnel's biprism experiment a mica sheet of refractive index 1.5 and thickness 6xx10^(-6)m is palced in the path of one of interfering beams as a result of which the central fringe gets shifted through five fringe widths. Then calculate the wavelength of light.
