In biprism experiment ,the eyepiece is placed at a distance of 1.2 metre from the sources.The distance between the virtual sources was found to be 7.5 xx 10^-4 m.Find the wavelength of light if the eye piece is to be moved transversely through a distance of 1.888 cm for 20 fringes.

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 eye piece is kept at a distance of 1.5 m from the slit and the distance of the 2nd dark band from the central point was found to be 1.2 cm. The sizes of the magnified and diminished images of slits produced by the convex lens are found to be 2.4 cm and 60 cm respectively. Calculate the wavelength of light used.

In a biprism experiment, the fringes are observed in the focal plane of the eye piece at a distance of 1.2m from the slits. The distance between the central bright band and 20th bright band is 0.4 cm. When a convex lens is placed between biprism and the eyepiece, the distance between the two vertical magnified images is found to be 0.9 cm. Determine the wavelength of light used.

In biprism experiment the distance between the two virtual images of the slit is 0.1 cm and the distance between the slit and biprism is 1 m .If the band width is 0.058 cm , calculate the wavelength of light .

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 .

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 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 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

In Young's experiment, the distance between two slits is 0.8mm and the distance of the screen from the slit is1.2 m. If the fringe width is 0.79 mm, the wavelength of light used is
