A monochromatic light of lambda=5000Å is inciden on two slits seperated by a distance of 5xx10^(-4)m. if a thin glass of thickness 1.5xx10^(-6) m and refractive index 1.5 placed between one of the slits and screen. The pahses difference introduced at the position of central maxima is

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 YDSE, light of wavelength lamda = 5000 Å is used, which emerges in phase from two a slits distance d = 3 xx 10^(-7) m apart. A transparent sheet of thickness t = 1.5 xx 106(-7) m , refractive indes n = 1.17 , is placed over one of the slits. Where does the central maxima of the interference now appear from the center of the screen? (Find the value of y?)

Figure shows a YDSE setup having identical slits S_(1) and S_(2) with d =5 mm and D = 1 m. A monochromatic light of wavelength lamda = 6000 Å is incident on the plane of slit due to which at screen centre O, an intensity I_(0) is produced with fringe pattern on both sides Now a thin transparent film of 11 mu m thickness and refractive index mu = 2.1 is placed in front of slit S_(1) and now interference patten is observed again on screen. After placing the film of slit S_(1) , the intensity at point O screen is :
