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?

Tick the correct option: In Young's double slit experiment the fringe width beta is :

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

In a Young's double slit experiment,the fringe width obtained is 0.6 cm,when light of wavelength 4,800 overset @A is used .If the distance between the screen and the slit is reduced to half,what should be the wavelength of light used to obtain fringes 0.0045 m wide?

What will be the effect on the fringes formed in Young's double slit experiment, if the apparatus is immersed in water,

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?
