In Young's double slit experiment what is the shape of interference fringes?

In Young's double slit experiment,the slits are 0.2 mm apart.The interfernce fringes for ligth of wavelength 6,000 overset @A are formed on a screen distanct 1.5 m from the sits.Calculate the fringe width.

What happens,if the monochromatic light used in Young's double slit experiment is replace by white light?

Show that in Young's double slit experiment for interference of light, the widths of the bright and dark fringes are equal.

In the Young's double slit experiment,the interference pattern is found to have an intensity ratio between brigth and dark fringe as 9.This i mplies that

How would the angular separation of interfernece frings in Young's double slit experiment change when the distance of separation between the slits and the screen is doubled?
