Question

Height of image is 4 qnd object is 2 then what will be magnified of lens

Answer 1

Answer:

$\boxed{\sf Magnification \ of \ lens \ (m) = 2}$

Given:

Height of image ($\sf h_i$ ) = 4 units

Height of object ($\sf h_o$ ) = 2 units

To Find:

Magnification of lens (m)

Explanation:

Formula of magnification:

$\boxed{ \bold{Magnification \: (m) = \frac{Height \: of \: image \: ( h_i ) }{Height \: of \: object \: ( h_o )} }}$

Substituting values of $\sf h_i$ & $\sf h_i$ in the equation:

$\sf \implies m = \frac{4}{2}$

$\sf \implies m = \frac{ \cancel{2} \times 2}{ \cancel{2}}$

$\sf \implies m =2$

$\therefore$

Magnification of lens (m) = 2
