A typical representation of a solar microscope with two lenses, one of which is the condenser and the other is a double convex lens with considerable Stock Vector Image & Art -
Two symmetrical double convex lenses A and B have same focal length, but the radii of curvature differ so that ${{R}_{B}}=0.9{{R}_{A}}$. If ${{\\mu }_{A}}=1.63$, Find $\\mu_B$.
An unsymmetrical double convex thin lens forms the image of a point object on its axis. Will the position of the image change if the lens is reversed ?
