Magnification of Mirror
Calculate magnification produced by a mirror.
m = -v / u = h′ / h
Formula Explanation
Magnification is the ratio of image height to object height.
Variables Explained
m = magnification; v = image distance; u = object distance.
Solved Example
v = -30 cm, u = -15 cm. Find m.
m = -(-30)/(-15) = -2.
