The distance between any two successive bright bands is

The distance between any two successive nodes or antinodes is

The distance between two successive base pairs is

The distance between two successive base pairs is

The distance between any two successive nodes or antinodes in stationary waves is

Light of wavelength 5000 Å is incident on a double with and the interference fringes are formed on a screen plated at a distance of 1m from the slits. If the distance between the two consecutive dark bands is 1 mm, then the distance between the two slits is
