In Young's double slit experiment ,the central bright fringe produced by ligth of wavelength `5,600 overset@A` shifts to the position of 5th brigth fringe,when thin transparent film of refractive index 1.28 is introduced in the path of light from one of two slits.Find the thickness of te film.

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 Young's double - slit exp[eriment ,two slits are 0.15 mm apart and illuminated by ligth of wavelenth 450 nm.The screen is 1 m away from the slits. Find the distance of the second bright fringe

In Yound's double slit experiment,wer get 15 fringes per cm on the screen,while using light of wavelength 5,600 overset @A (sodium lamp).How many fringes per cm we get with ligth of wavelength 7,000 overset@A ?

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?

The two slits in Young's double slit experiment are seprated by a distance of 0.03 cm.When light of wavelength 5,000 overset@A falls on the slits,nd interference pattern is produced on the screen 1.5 m away.Find the distance of 4th bright fringe from the central maximum.

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 angular position of the fifth minima

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 angular position of the third maxima,

In a Young's double slit experimnet,red ligth of wavelength 6,000 overset @A is used and the nth bright fringe is obtained at a point P n the screen .Keeping the same setting,the source is replaced by green light of 5,000 overset@A and now (n+1) th brigth fringe is obtained at the point P .Calculate the value of n.

In Young's double - slit exp[eriment ,two slits are 0.15 mm apart and illuminated by ligth of wavelenth 450 nm.The screen is 1 m away from the slits. Find the distance of the second dark fringe from the central maximum.
