In Fresnel's biprism experiment, when the distance between the slit aperture and eye is increased, then distance between the fringes

In a biprism experiment, when a convex lens was placed between the biprism and eyepiece at a distance of 30cm from the slit, the virtual images of the slits are found to be separated by 7mm . If the distance between the slit and biprism is 10cm and between the biprism and eyepiece is 80cm , find the linear magnification of the image.

In a double slit experiment to find the separation between slits by displacement method, the separations of images of slits were found to be 16mm and 9mm respectively. The actual separation between slits will be

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.

The following figure shows the positions of a point object O, two lenses, a Plane mirror and the final image I which coincides with the object. The focal length of the convex lens is 20 cm. Calculate the focal length of the concave lens. The distance between the first and the sixth bright fringes formed in Young's double slit experiment ( measured by a spectrometer ) is found to be 12.5 mm. The separation between the slits is 0.12 mm and the distance of the screen from the slits is 60 cm. Calculate : The fringes width
