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.

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.

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

If one of the slits in Young's experiment is covered, what effect will be intensity of light at the centre of the screen?

A thin glass plate of thickness is (2500)/3lamda ( lamda is wavelength of light used) and refractive index mu=1.5 is inserted between one of the slits and the screen in Young's double slit experiment. At a point on the screen equidistant from the slits, the ratio of the intensities before and after the introduction of the glass plate is :

In Young's double slit experiment, the intensity of central maximum is I . What will be the intensity at the same place if one slit is closed ?

In Young's double slit experiment, the intensity of central maximum is I . What will be the intensity at the same place if one slit is closed ?
