Question

If a concave mirror produces a real image of size 3.6 cm of an object of size 1.2 cm, then the magnification produced by the mirror is-

Answer 1

Explanations & Calculations

• Magnification produced by mirrors or lenses is given by

$\qquad\qquad \begin{aligned} \small M&=\small \frac{H_{image}}{H_{object}} \end{aligned}$

• Then, following this, we can get the magnification of the mirror.

$\qquad\qquad \begin{aligned} \small M&=\small \frac{3.6cm}{1.2\,cm}\\ &=\small \bold{3} \end{aligned}$

• The magnification is 3 times
