Derive an expression for path difference in Young' s double slite experiment and obtain the conditions for constructive and destructive inteference at a point on the screen.

In Young's double slit experiment derive the condition for (i) constructive interference and (ii) destructive interference at a point on the screen.

Mention the conditions to form constructive and destructive interference patterns in Young's experiment related to interence of light.

If young' s double slit experiment is performed using white light, then

In Young's double slit experiment what is the path difference between the two light waves forming 5th bright band on the screen ?

How does the fringe width in Young's double slit experiment change when the distance of separation between the slits and screen is double ?

In Young's double sllit experiment, What in the effect on the interference pattern if, The distance between the screen and the plane of slits is doubled.

Using monochromatic light of wavelength 4000 Å fringes of width 0.1 mm are formed on the screen in Young's double slit experiment . If the screen is now shifted to twice the previous distance the what will be the fringe width of the interference pattern when a wavelength of 6000 Å is used ?

To prodce inteference fringes in Young' s double slit experiment light consisting of two wavelengths of 6500 Å and 5200 Å is used. (i) Determine the distance of the third maxima from the central maxima for light of wavelength 6500 Å . (ii) At what minimum distance from the central maxima will the bright points (maxima) for two waves superpose? Given that distance between the two slits is 2 mm and the distance of the screen from the plane of the slits is 120 cm.
