    Mark the correct options (i) If the far point goes ahead, the power of the divergent lens should be reduced (ii) If the near point goes ahead, the power of the convergent lens should be reduced (iii) If the far point is 1m away from the eye, divergent lens should be used (iv) If the near point is 1m away from the eye, divergent lens should be used

    The distance between an object and a divergent lens is m times the focal length of the lens. The line r magnification produced by the lens is:

    A diverging lens with magnitude of focal length 25 cm is placed at a distance of 15 cm from a converging lens of magnitude of focal length 20 cm . A beam of parallel light falls on the diverging lens. The final image formed is.

    Assertion (A) : A convex lens is called a convergent lens but a concave lens acts as a divergent lens. Reason (R) : A convergent lens is that which always forms a real image of a real object and a divergent lens is that which can never form a real image.
