An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position of the image formed by the mirror.
Solution
u = - 10cm; f = +15 cm
$\dfrac{1}{f}$ = $\dfrac{1}{v}$ + $\dfrac{1}{u}$
1/15 = $\dfrac{1}{v}$ + 1/(-10 cm)
$\dfrac{1}{v}$ = 1/15 cm + 1/10 cm
v = + 6 cm
Image is formed behind the mirror.
