In a biprism experiment with sodium light,bands of width `0.0195cm` are observed at`100cm` from slit.On introducing a convex lens `30cm` away from the silt between biprism and screen,two images of the slit are seen`0.7cm`apart of `100cm` distance from the slit .Calcualte the wavelength of sodium light .

In an experiment with Fresnel biprism sodium light is used and bands 0.0196 cm in width are observed at the distance of 100 cm from the slit. A convex lens is placed between the biprism and the slit. If the distance between the slit and screen is one meter, the magnified distance apart of the images is found to be 0.7 cms, the lens being 30 cm from the slit, calculate the wavelength of light.

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 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 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 Young's double slit experiment, the slits are seperated by 0.24 mm. The screen is 1.2m away from the slits. The fringe width is 0.3 cm. Calculate the wavelength of the light used.

In a biprism experiment, when a convex lens is placed between the biprism and eyepiece at a distance of 30 cm from the slit, the virtual images of the slits are 7mm apart. If the distance between the slit eyepiece is 90 cm, find the linear magnification of the image.

In a Fresnel's biprism experiment, sodium light of wavelength 5832 Å is used. Calculated the fringe width, given the distance between the screen and the biprism =120 cm and the distance the two sources=0.04 cm.

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 ?
