364847 A wire mesh consisting of very small squares is viewed at a distance of \(8\;cm\) through a magnifying converging lens of focal legnth \(10\;cm\), kept close to the eye. The magnification produced by the lens is

364848 One surface of a lens is convex and the other is concave. If the radius of curvatures are \({r_1}\) and \({r_2}\) respectively, the lens will be convex, if

364849 The radius of curvature of convex surface of a thin plano-convex lens is \(15\;cm\) and refractive index of its material is 1.6. The power of the lens will be

364850 Figure given below shows a beam of light converging at point \({\rm{P}}\). When a concave lens of focal length \({\rm{16}}\;{\rm{cm}}\) is introduced in the path of the beam at a place \(O\) shown by dotted line such that \(OP\) becomes the axis of the lens, the beam converges at a distance \(x\) from the lens. The value \(x\) will be equal to
