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 a slab of mica of refractive index mu and thickness of t is introduced in the path of light from one of the slits, then number of fringes formed on the screen will –

Two glass plates of refractive indices 1.5 and 1.6 are introduced in the paths of the two interfering beams in an interference experiment.If the central fringe is not shifted.The ratio of the thickness of the plates is

In a Young's double slit experiment 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 slits and screen is doubled. It is found that the distance between successive maxima now is the same as observed fringe shift upon the introduced of the mica sheet . Calculate the wavelength of the monochromatic light used in the experiment .

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 ideal double-slit experiment, a glass plate (refractive index = 1.5) of thickness t is introduced in the path of one of the interfering beams (wavelength lambda ), intensity at the position where the central maximum occurred previously remains unchanged. The minimum thickness of the glass plate is

In the ideal double-slit experiment, when a glass-plate (refractive index 1.5) of thickness t is introduced in the path of one of the interfering beams (wavelength lambda ), the intensity at the position where the central maximum occurred previously remains unchanged. The minimum thickness of the glass-plate is
