Conisder a two slit interference arrangement as shown in Fig.6.07.

Here,CO=D and `S_1C=SC_2=D`i.e. the distance of the screen from the slits is half the distance between the slits.Obtain the value of D in terms of `lamda`,such that the first minima on the screen falls at a distance D from the cetreO.

Consider a two slit interference arrangements (Fig. EP 10.18) such that the distance of the screen from the slits is half the distance between the slits. Obtain the value of D in terms of lambda such that the first minima on the screen falls at a distance D from the center O.

In Young's experiment,the distance of screen from the two slits is 1.0 m.when a ligth of wavelength 6,000 @A is allowed to fall on the silts,the width of the fringes obtained on the screen is 2.0 mm.Determine distance between the two 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.

A parallel beam of ligth of wavelength 600 nm is incident normally on a slit of width d .If the distance between teh slit and the screen is 0.8 m and the distance fo teh second order maximum from teh centre of the screen is 15 mm,calculate the width of the slit.
