In Young's double slit experiment with monochromatic light, fringe width is found to be 0.4 mm in air. The whole system is immersed in water, what will be the new fringe width?

In Young's double silt experiment, the fringe width obtained is 3 mm in air. If the apparatus is immersed in water (mu=4//3) ,what will be the new fringe width?

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

In a double-slit experiment the angular width of a fringe is found to be 0.2^@ on a screen placed 1 m away. The wavelength of light used is 600 nm. What will be the angular width of the fringe if the entire apparatus is immersed in water? Take refractive indexof water to be 4/3 .

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

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.
