A narrow beam of 100eV electrons is fired at two parallel slits very close to each other. The distance between the slits is 10Å. The electrons waves after passing through the slits interfere on a screen 3m away from slits and form interference fringes. Find the width of the fringe.

In a double slit experiment, the distance between the slits is d. The screen is at a distance D from the slits. If a bright fringe is formed opposite to one of the slits, its order is

In a double slit experiment, the distance between the slits is d. The screen is at a distance D from the slits. If a bright fringe is formed opposite to one of the slits, its order is

A beam of monochromatic light of wavelength 500 nm falls on two parallel slits. The distance between the slits is 0.15 mm. Determine the width of the interference fringes in mm unit on a screen placed at a distance of 1.5 m from the plane of the slits.

A long narrow horizontal slit is placed 1 mm above a horizontal plane mirror. The interference between the light coming directly from the slit and that after reflection is seen on a screen 1.0 m away from the slit, Find the fringe-width if the light used has a wavelength of 700 nm.

A beam of light consisting of two wavelenths, 6500 Å and 5200 Å is used to obtain interference fringes in a Young's double slit experiment (1 Å = 10^(-10) m). The distance between the slits is 2.0 mm and the distance between the plane of the slits and the screen in 120 cm. (a) Find the distance of the third bright frings on the screen from the central maximum for the wavelength 6500 Å (b) What is the least distance from the central maximum where the bright frings due to both the wavlelengths coincide ?
