In Young's double slit experiment, the width of one of the slits is slowly increased to make it twice the width of the other slit. Then in the interference pattern:
The sequence of ionic mobility in aqueous solution is
The two slits are 1 mm apart from each other and illuminated with a light of wavelength 5 x 10-7 m. If the distance of the screen is 1 m from the slits, then the distance between third dark fringe and fifth bright fringe is
