In Young's double slit arrangement, slits are separated by a gap of 0.5 mm, and the screen is placed at a distance of 0.5 m from them. The distance between the first and the third bright fringe formed when the slits are illuminated by a monochromatic light of 5890 X is :

Two slits separated by a distance of 1 mm are illuminated with light of wavelength 6.0 xx 10^-7 m . The interference fringes observed on a screen placed 1 m from the slits. The distance between third dark fringe and the fifth bright fringe is equal to :

Two slits, 4 mm apart, are illuminated by light of wavelength 6000 Å . What will be the fringe width on a screen placed 2 m from the slits
