Question

object distance and image distance of lens are -60 cm and -20 cm respectively then the magnification of lens will be
​

Answer 1

Answer:-

• Object distance=u=-60cm
• Image Distance=v=-20cm

We know that

$\boxed{\sf Magnification=-\dfrac{v}{u}}$

$\\ \rm\longmapsto Magnification=-\dfrac{-60}{-20}$

$\\ \rm\longmapsto Magnification=-\dfrac{60}{20}$

$\\ \rm\longmapsto Magnification=-3$
