Question

0.5 was the Magnification of an image formed on a rear view mirror When the Object was placed at a distance of 30cm.
Find the image distance .
step by step ? ​

Answer 1

REQUIRED ANSWER :

We have magnification = 0.5 , distance of objects = 30 cm

We know that convex lens = u = -30 cm

$\left( m = - ( \frac{v}{u} \right)$

$\mapsto$ 0.5 = $\color{orange}( \frac{v}{ - 30} )$

$\looparrowright$ $\color{red}{ \: 0.5 = \frac{v}{30}}$

$\looparrowright$ $\color{grey}{v = 0.5 \times 30}$

$\looparrowright$ $\color{blue}{v = 15cm}$
