A thin perfectly transparent glass sheet of thickness t and refractive index mu is pasted on one of the two identical slits. If the intensity of light at the centre of the screen is `I_(0)` in the absence of glass sheet, the intensity at O as a function of thickness of the glass plate is

A thin glass plate of thickness t and refractive index mu is inserted between screen and one of the slits in a young's experiment. If the intensity at the centre of the screen is I, what was the intensity at the same point prior to the introduction of the sheet.

When a thin transparent plate of thickness t and refractive index mu is placed in the path of one the two interfering waves of light, then the path difference changes by

A thin glass plate of thickness t and refractive index mu is between screen &one of the slits in young's experiment.if the intensity at the center of the screen is I ,was the intenstity at the same point prior to the introduction of the sheet. (b) One slit of a young's experiment is covered by a glass plate (mu_(1)=1.4) and the other by another glass plate (mu_(2)=1.7) of the same thickness. The point of central maxima of the screen,before the plates were introduced is now occupied by the third bright fringe.Find the thicknes of the thickness of the plates.the wavelength of light used in 4000Å .

A monochromatic light of lambda=500 nm is incident on two identical slits separated by a distance of 5xx10^(-4)m . The interference pattern is seen on a screen placed at a distance of 1 m from the plane of slits. A thin glass plate of thickness 1.5xx10^(-6)m and refractive index mu=1.5 is placed between one of the slits and the screen. Find the intensity at the centre of the screen if the intensity is I_(0) in the absence of the plate. Also find the lateral shift of the central maxima and number of fringes crossed through centre.

In Young’s double slit experiment a monochromatic light of wavelength lambda from a distant point source is inci- dent upon the two identical slits.The interference pattern is viewed on a distant screen. Intensity at a point P is equal to the intensity due to individual slits (equal to I_(0) ). A thin piece of glass of thickness t and refractive index mu is placed in front of the slit which is at larger distance from point P, perpendicular to the light path. Assume no absorption of light energy by the glass. (a) Write intensity at point P as a function of t. (b) Write all values of t for which the intensity at P is minimum.
