Question
Write down the magnification formula for a lens in terms of object distance and image distance. How does this magnification formula for a lens differ from the corresponding formula for a mirror?
$\text{m}=\frac{\text{v}(\text{distance of image})}{\text{u}(\text{distance of object})}$
Magnification fomula for a mirror has a minus sign (-) but the Magnification fomula for a lens has to minus sign. Magnification fomula for a mirror is:$\text{m}=-\frac{\text{v}(\text{distance of image})}{\text{u}(\text{distance of object})}$
