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?

In a young's double slit experiment two slits are made one millimeter apart and the screen is placed one meter away. What is the fringe separation when monochromatic light of wavelenght 500nm is used?

Yellow light of wavelength 6000Å produces fringes of width 0.8 mm in Young's double slit experiment. What will be the fringe width of the light source if it is replaced by another monochromic source of wavelength 7500Å and sepearation between the slits is doubled?

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

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?
