In YDSE, what is the ratio of fringe width for bright and dark fringes ?

In YDSE experiment a uniform intensity light beam is incident on slit plane which has two slits having width ratio 9 : 4 . Find the ratio of intensities of bright and dark fringes on screen. [25]

Derive an expression for fringe width for Bright and Dark bands.

Two waves whose intensities are in the ratio 9:1 interfere.find the ratio of the intensities of bright and dark fringes.

In an interference experiment, the ratio of the intensities of the bright and dark fringes is 16:1. The ratio of the amplitudes due to the two slits is

In an interference experiment,the ratio of the intensities of the bright and dark fringes is 16 .The ratio of the amplitudes due to the two slits is

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