In a biprism experiment without disturbing other settings, only distance between the slit and micrometer eyepiece is increased by 50%. What will be the change in the fringe width if initially it was 0.3mm ?

In a biprism experiment , the band width is found to be increased by 25% of the initial . If the distance between slit and eyepiece is increased by 20 cm then the initial distance between slit and eyepiece is

In a biprism experiment, the distance between the slit and screen is 1 m and distance between the images of the slit is 0.274 mm. If the fringewidth is 0.2 cm, the wavelength of light is

In a biprism experiment , the slit is illuminated by a light of wavelength of 5000 overset (@)(A) . The distance between the slit and eyepiece is 1 m . If the distance between the two virtual sources is 0.25 cm , then distance between fifth bright band on one side and the sixth dark band on the other sideof the central bright band will be

In a biprism experiment, the width of fringe is 0.12 mm when the eyepiece is at a distance of 100 cm from the slit. What would be the width of the fringe if the eyepiece is moved towards the slit by 25 cm ?

In a biprism experiment , the distance between the virtual images of the slits is 2.5 mm and the eyepiece is at a distance of 1 m from the slits . If the fringe width is 0.3 mm then the frequency of source of light is

In a biprism experiment the distance between the slit and the eyepiece is 100 cm. When a convex lens is introduced between the biprism and the eyepiece, images of the slit obtained in the two positions of the lens are 2 xx 10^-3 m and 4.5 xx 10^-3m apart.If the wavelength of light used is 6000 overset (@)(A) , find the distance between the fourth bright band on one side and fourth dark band on the other side of central bright band.

In a biprism experiment, the fringe width is 0.4 mm, when the eyepiece is at a distance of 1meter away from the slit. The change in fringe width, if the eyepiece is moved through a distance of 25 cm towards the byprism without changing any other arrangement is

Following observations were made in a biprism experiment. Distance between virtual images of slit = 5 mm. Distance between slit and eyepiece = 75 cm. Distance between second dark band and tenth dark band of same side of centre is 0.576 mm. Calculate wavelength of light used.

In biprism experiment,the slit is illuminated by a light of wavelength 5890 overset (@)(A) . The distance between the slit and eyepiece is 80 cm. The two virtual images of the slit are formed 0.2 cm apart. Calculate the change in the bandwidth if the eyepiece is displaced by 10 cm away from the slit.

In a biprism experiment the distance between the slit and eyepiece is 1 m and two virtual sorces formed by the biprism are 0.5 mm apart . If the wavelength of light is used is 6000 overset (@)(A) , find the band width .
