Two slits are 1mm apart and a screen is placed at some distance. When the slits are illuminated with light of wavelength 500nm, fringe separation obtained on the screen is 0.5mm. What is the distance between the screen and the slits?

In double slit experiment using light of wave length 320 nm the angular width of a fringe formed on a distant screen is 0.1^@ . What is the spacing between the two slits?

In a double slit experiment, the two slits are 1 mm apart and the screen is place 1 m away. A monochromatic light of wavelength 500 nm is used. What will be the width of each slit for obtaining ten maxima of double slit within the central maxima of single slit pattern?

Two slits are made 1mm apart and is placed 0.8m away in Young's double slit experiment. What is the fringe separation when blue-green light of wavelength 500 mn is used?

A beam of light consisting of two wavelengths 6500 A ˙ and 5200 A ˙ is used to obtain fringes in a Young's double slit experiment.Find the distance of the third bright fringe on the screen from central maximum for the wavelength 6500 A. The distance between the slits is 2mm and the distance between the plane of the slits and the screen is 120 cm

In Young's double slit experiment using light of wavelength 5000Å, the fringe width is 0.6 cm. If the distance between the slit abd screen is reduced to half , calculate the new fringe width.

In a Young's double slit experiment, the slits are 0.03 cm apart and the screen is placed 1.5m away from the plane of the sources. The distance between the central bright fringe and the fourth bright fringe is measured to be 1 cm. Determine the wavelength of the light used.
