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?

In Young's doule slit experiment,the slits are 3 m from the screen.The width of the fringes observed with ilght of wavelength 6,000 overset @A is 2 mm.What is the separation of the slits?

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 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 a Young's double slit experiment, the slits are separated by 0.03 cm and the screen is placed 1.5 m away. The distance between the central fringe and the fourth bright fringe is 1 cm. Determine the wavelength of light used in the experiment.

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 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 experiment, the slits are separeted by 0.56 mm and the screen is places 2.8m away. The distance between the central bright fringe and the fifth bright fringe is 1.5 cm. Find the wavelength of light used.

In a Young's double slit experiment the slit are 0.2 mm apart and the screen is 1.5 m away.It is observed that the distance between the central brigth fringe and fourth dark fringe is 1.8 cm .Find the wavelength of light used.
