Question

4. An object 3 cm tall is placed 8 cm in front of a convex mirror of focal length 10 cm.

(i) Draw ray diagrams to locate the image formed.

(ii) What is the magnification of the image formed? (Hint: Magnification = image height (II')/object height (OO') or image distance/object distance or v/u.) 

Answer 1

The magnification is

$$M=\frac{v}{u}=\frac{1.8}{3}=0.6.$$
