A plane monochromatic light wave falls normally on a diaphragm with two narrow slits separated by 2.5mm. The fringe pattern is formed on a screen 100 cm behind the diaphragm. By what distance will these fringes be displaced, when one of the slits is covered by a glass plate ` (mu = 1.5)` of thickness `10 mu m ?`

A plane monochromartic light wave falls normally on a diaphragm with two narrow slist separated bya distance d = 2.5 mm . A fringe pattern is formed on a screen placed at a distance l = 100 cm behind the diaphragm. By what distance and in which direction will these fringes be dispalced when one of the slits is covered by a glass plate of thickness h = 10mu m ?

A plane monochromatic light falls normally on a diaphragm with two narrow slits separated by a distance d = 2.5 mm. A fringe pattern is formed on the screen placed at D = 100 cm behind the diaphragm. If one of the slits is covered by a glass plate of thickness 10mu m , then distance by which these fringes will be shifted will be :

Monochromatic light from a narrow slit illuminates two narrow slit 0.3 mm apart producing an interference pattern with bright fringes 1.5 mm apart on a screen 75 cm away. Find the wavelength of the light. How will the fringe width altered if the distance of the screen is doubled .

Monochromatic light from a narrow slit illuminates two parallel slits producing an interference pattern on a screen. The separation between the two slits is now doubled and the distance between the screen and the slits is reduced to half. The fringe width

A monochromatic light of lambda = 500 Å is incident on two indentical slits separated by a distance of 5 xx 10^(-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 1.5 xx 10^(-6) m and refractive index mu = 1.5 is placed between one of the slits and the screen . Find the intensity at the center of the screen.
