(a) A point object is placed in front of a double convex lens ( of refractive index n = n_(2) // n_(1) with respect to air ) with its spherical faces of radii of curvature R_(1) and R_(2) . Show the path of rays due to refraction at first and subsequently at the second surface to obtain the formation of the real image of the object. Hence obtain the lens-maker's formula for a thin lens. A double convex lens having both faces of the same radius of curvature has refractive index 1.55. Find out the radius of curvature of the lens required to get the focal length of 20cm.

A point object O is kept at a distance of OP=u . The radius of curvature of the spherical surface APB is CP=R. The refractive index of the media are n_(1) and n_(2) which are as shown in the diagram Then, (1) if n_(1)gtn_(2) , image is virtual for all values of u. (2) if n_(2)=2n_(1) , image is virtual when Rgtu . (3) the image is real for all values of u,n_(1) and n_(2) . Here, the correct statement/s is are
