In Young's double slit experiment,light of wavelength`5,000 overset @A` is used.The screen on which fringes are projected is 1.5 m from the centre of the narrow slits. The third bright band on the screen is formed at a distance of 1 cm from the central bright band calculate the separation between the slits.

In Young's double slit experiment,ligth of wavelnegth 6,000 overset @A is used to get an interference pattern on a screen.The fringe width changes by 1.5 mm,when the screen is brougnt towards the double slit by 50 cm.Find the distance between the two slits.

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 a Young,s double split experiment, light of wavelength 4000 overset@A is incident on a double slit. If the overall separation of 10 fringes on a screen 100 cm away is 0.4 cm. Find the distance between the two 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?
