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. |

Answer» From the magnification formula `(d_(1))/(d)=(v)/(u)` `(v)/(u)=(60)/(30)` `(v)/(u)=2` Linear magnification `=2` |
