In YDSE, when the entire apparatus is immersed in water, what happens to fringe width ?

If the apparatus used in YDSE is immersed in water then what will happen to the fringe width.

In Young's experiment fringe width is 2 mm for light of wavelength 6000 overset(@)(A) . Calculate the fringe width if the entire apparatus is immersed in water of refractive idex 4/3.

In young's double slit experiment the slits are illumated by light of wavelength 5890^(@) A and the distance between the fringes obtained on the screen is 0.2^(@) . If the whole apparatus is immersed in water then the angular fringe width will be, if the refractive index of water is 4//3

In young's double slit experiment the slits are illumated by light of wavelength 5890^(@) A and the distance between the fringes obtained on the screen is 0.2^(@) . If the whole apparatus is immersed in water then the angular fringe width will be, if the refractive index of water is 4//3

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 Youngs 's double slit experiment, the fringe width obtained by using monochromatic light of wavelength 6000 Å is 2 mm. if the whole apparatus is immersed in water of R.I. 1.33, then the change in fringe width will be

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 .

Assertion (A) : If the whole apparatus of YDSE is immersed in a liquid, then the fringe width will decrease Reason (R ) : The wavelength of light in water is more than that of air.
