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.

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.

What happens to fringe width, whne the separation between the slits as well as distance of the screen from the slit are halved?

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.

A beam of ligth consisting of two wavelength 4,800 overset@A and 6,000 overset@A is used to obtain interfernce fringes in a double slit experiment.The distnce between the slits is 1.8 mm and the distance of screen from the plane of slits is 1.2 m Find the distance of the third bright frings on the screen from the central maximum for the wavelength 6,000 overset @A .

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

In a Young's double slit experiment ,the distance between the slits and the screen is 1 m.If the distance between the slits is 5 mm,the fringe width is found to be 0.1 mm.Calculate the wavelength of the light used.

A beam of ligth consisting of two wavelength 4,800 overset@A and 6,000 overset@A is used to obtain interfernce fringes in a double slit experiment.The distnce between the slits is 1.8 mm and the distance of screen from the plane of slits is 1.2 m What is the lest distance from the centre of the screen,where the brigth fringes due to both the wvelength coincide?

In a single slt diffraction pattern,how is the width of cetral bright maximum changed,when the distance between the slit and the screen is increased

A beam of light consisting of two wavelegnths, 6,500 overset @A and 5,200 overset @A is used to obtain interfrerence fringes in a Young's double slit experirmejnt.The distance between the slits and the screen is 120 cm. Find the distance of third bright fringe on the screen from the central maximum for the wavelength 6,500 overset @A .
