h1

this is magnification of lenses.

Answer 2

For magnification of lens, magnification = the height of the image divided by the height of the object.

Explanation:

As we know,

$\frac{1}{f} =\frac{1}{v} -\frac{1}{u}$

Where,

f = focal length of the lens,

u = distance of the object from the lens

v = distance of the image is formed from the lens.
