A converging lens has a focal length of $0.12 m .$ To get an image of unit magnification the object should be placed at what distance from the converging lens?

Options:

Answer:

Solution:

Given: $f = + 0.12 m$ (converging lens),

To get a unit magnification from a converging lens, i.e., convex lens, the object must be placed at $2 f .$

$u = 2 \times 0.12 m = 0.24 m$
