In Young' double slit experiment, the expriment, the angular width of a fringe formed on a distant screen is `0.5^@`. The wavelength of light used is `6000 overset@A`. What is the spacing between the slits?

In double-slit experiment using light of wavelength 600 nm, the angular width of a fringe formed on a distant screen is 0.1^@ . What is the spacing between the two slits?

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

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 .

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,usin light of wavelength 400 nm,interference fringes of width X are obtained .The wavelength of light is increassed to 600 nm and the separation between the slits is halved.If one wants the observed fringe width on the screen to be the same in the two caes,find the rati of the distance between the screen and the plane of the interfering sources in the two arrangements.

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
