In Young's double-slit experiment, let A and B be the two slit. A thin film of thickness t and refractive index mu is placed in front of A. Let beta = fringe width. Then the central maxima will shift

In a YDSE experiment the two slits are covered with a transparent membrane of negligible thickness which allows light to pass through it but does not allow water. A glass slab of thickness t=0.41 mm and refractive index mu_(g)=1.5 is placed infront of one of the slits as shown in the figure. The separation between the slits is d=0.30 mm . The entire space to the left of the slits is filled with water of refractive index mu_(w)=4//3 . A coherent light of intensity I and absolute wavelength lambda=5000Å is being incident on the slits making an angle 30^(@) with horizontal. If screen is placed at a distance D=1m from the slits, find ( a ) the position of central maxima. ( b ) the intensity at point O .

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.

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 :
