In young's double slit experiment 'the wavelength of red light is`7800overset(@)A` and that of blur light is `5200overset(@)A`.the value of n of which nth bright band due to red light coincides with (n+1) bright band due to blue light is:

In a Young's double slit experiment, the source is white light. One of the holes is covered by a red filter and another by a blue filter. In this case:

Show that in Young's double slit experiment for interference of light, the widths of the bright and dark fringes are equal.

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,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 a Young's double slit experiment,the separation betwen the two slits is d and the wavelength of the light is lambda .The intensity of light falling on the slit 1 is four times the intesntiy of light falling on slit 2.Choose the correct choice(s).

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' 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?
