282519 If a convex lens of refractive index 1.44 is dipped in liquid of refractive index 1.49 , then it behaves as:

282520 A convergent doublet of separated lens, corrected for spherical aberration, are separated by \(2 \mathrm{~cm}\) and has an equivalent focal length of \(10 \mathrm{~cm}\). The focal length of its component lenses are :

282521 A plano-convex lens has refractive index 1.5 and radius of curvature \(50 \mathrm{~cm}\). What is focal length of lens?

282522 A Plano convex lens fits exactly into Plano concave lens as shown in figure. Their plane surfaces are parallel to each other. If the lens are made of different materials of refractive indices \(1.6 \& 1.5\) respectively. If \(R\) is the radius of curvature of curved surface of lenses. Then the focal length of the combination.
