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

What happens to fringe width,when the separation between the sources is increased?

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 Young's double slit experiment the width of the fringes obtained with ith of wavelength 4,500 overset@A is 1.8 mm.If the distance between the two slits is 0.3 mm,find the distance of the screen from the slits.What will be the fringe width,if the enitre apparatus is immersed in water of refraction index 4//3 .

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?

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,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.

In Young's double-slit experiment, the separation of slits is doubled and the distance of the slits and screen is halved. How will its affect the fringe width?

What happens to fringe width in the Young's double slit experiment,if its is performed in glycerine insteaad of air?

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 a two-slit experiment with monochromatic light, fringes are obtained on the screen placed at some distance form the slits. If the screen is moved by 5 xx 10^-2 m towards the slits, the change in fringe width is 3 xx 10^-5 m . If the distance between the slits is 10^-3 m , calculate the wavelength of the light band.
