A double slit apparatus is immersed in a liquid of refractive index 1.33. It has slit separation of 1 mm and distance between he plane of slits and screen is 1.33 m. The slits are illuminated by a parallel beam of light whose wavelength in air is `6300 oversetcircA`
Calculate the fringe width.

A double slit apparatus is immersed in a liquid of refractive index 1.33. It has slit separation of 1 mm and distance between he plane of slits and screen is 1.33 m. The slits are illuminated by a parallel beam of light whose wavelength in air is 6300 oversetcircA One of the slits of the apparatus is covered with a thin glass sheet of refractive index 1.53. Find the smallest thickness of the sheet to bring the adjacent minimum on the axis.

If the apparatus is immersed in a liquid of refractive index 1.35,what would be the width of the central fringe?

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 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, the separation of slits is doubled and the distance of the slits and screen is halved. How will its affect the fringe width?

in a Youing's double slit experiment,bicromatic light of wavelengths 400 nm and 560 nm are used.The distance between the slits is 0.1 mm and the distance between the plane of the slits and screen is 1.0m. the minimum distance between two successive regions of complete darkness is

In Young's double slit experiment the width of the fringes obtained with ith of wavelength 4,500 overset@A is 1.8 mm.If the distance between the two slits is 0.3 mm,find the distance of the screen from the slits.What will be the fringe width,if the enitre apparatus is immersed in water of refraction index 4//3 .

In Young's double slit experiment,the slits are 0.2 mm apart.The interfernce fringes for ligth of wavelength 6,000 overset @A are formed on a screen distanct 1.5 m from the sits.Calculate the fringe width.

In a Young's double slit experiment,interfernce fringes were produced on a screen placed at 1.5 m from the two slits 0.3 mm apar and illuminated by ligth of 6,400 overset@A .Find the fringe width.

What happens to fringe width, whne the separation between the slits as well as distance of the screen from the slit are halved?
