An object of height $h = 5 cm$ is located at a distance $a = 12 cm$ from a concave mirror with focal length 10 cm. Find the height of the image.

Answer:

Solution:

u = - 12 cm, f = - 10 cm

\frac{1}{v} = \frac{1}{f} - \frac{1}{u} = - \frac{1}{10} + \frac{1}{12} = - \frac{1}{60}

v = - 60 cm

m = - \frac{v}{u} = - 5

Height of image = ∣ m ∣ h = 5 \times 5 = 25 cm
