An object is placed 18 cm from a convex mirror of radius of curvature 18 cm. Find the position of image.

Open in App

Solution

u = -18 cm

f = 9 cm

Mirror formula $\frac{1}{f}$ = $\frac{1}{u}$ + $\frac{1}{v}$

$\frac{1}{v}$ = $\frac{1}{9}$ + $\frac{1}{18}$

v = 6 cm.

An object is placed 18 cm from a convex mirror of radius of curvature 18 cm. Find the position of image.

u = -18 cm f = 9 cm Mirror formula 1f = 1u + 1v 1v = 19 + 118 v = 6 cm.

u = -18 cm

f = 9 cm

Mirror formula $\frac{1}{f}$ = $\frac{1}{u}$ + $\frac{1}{v}$

$\frac{1}{v}$ = $\frac{1}{9}$ + $\frac{1}{18}$

v = 6 cm.
