Question 103: Ray Optics

Question

Two identical objects are placed in front of convex mirror and concave mirror having same radii of curvature of 12 cm , at same distance of 18 cm from the respective mirrors. The ratio of sizes of the images formed by convex mirror and by concave mirror is :

Accepted Answer

$$\begin{aligned}
& 	ext { Using } m=\frac{f}{u-f} \
& m_1=\frac{6}{18-6}=\frac{1}{2}
\end{aligned}$$
$\mathrm{m}_2=\frac{6}{18+6}=\frac{1}{4} \quad 	herefore \frac{\mathrm{~m}_2}{\mathrm{~m}_1}=\frac{1}{2}$
