In Young's double-slit experiment, the separation of slits is doubled and the distance of the slits and screen is halved. How will its affect the fringe width?

In Young's double slit experiment,the sepaation between the slit is halved and distance between the slits and screen is doubled.The fringe width is

In a Young's double slit experiment,the separation betwen the two slits is d and the wavelength of the light is lambda .The intensity of light falling on the slit 1 is four times the intesntiy of light falling on slit 2.Choose the correct choice(s).

In a Young's double slit experiment ,the distance between the slits and the screen is 1 m.If the distance between the slits is 5 mm,the fringe width is found to be 0.1 mm.Calculate the wavelength of the light used.

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

A light of wavelength 1300 A^@ is used to illuminate two slits as a distance of 0.3 mm apart in Young.s double slit experiment. Fringes observed on a screen are found to be 1.3 mm apart. Find the distance of screen from the slits and also find the fringe width if the distance of screen is doubled now.

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