364812 Assertion :
A convex lens is made of two different materials. A point object is placed on the principal axis. The number of images formed by the lens will be two.
Reason :
The image formed by convex lens is always virtual.

364813 An object is kept at a distance of \(16\;cm\) from a thin lens and the image formed is real. If the object is kept at a distance of \(6\;cm\) from the same lens, the image formed is virtual. If the sizes of the image formed are equal the focal length of the lens will be

364814 Assertion :
A double convex lens \((\mu = 1.5)\) has focal length \(10\;cm\). When the lens is immersed in water \((\mu = 4/3)\) its focal length becomes \(40\;cm\).
Reason :
\(\frac{1}{f} = \frac{{{\mu _g} - {\mu _m}}}{{{\mu _m}}}\left( {\frac{1}{{{R_1}}} - \frac{1}{{{R_2}}}} \right)\)

364815 A double convex lens made of glass (refractive index \(n=1.5\) ) has both radii of curvature of magnitude \(20\;cm\) incident light rays parallel to the axis of the lens will converge at a distance \(L\) such that
