| 02. A square wire of side 3.0 cm is placed 25 cm away from a concave mirror of focal length 10 cm. What is the area enclosed by the image of the wire? Given: The centre of the wire is on the axis of the mirror, with its two sides normal to the axis. |
| |
| Suggested solution: |
| |
| u = -25 cm, f = -10 cm v = ? |
| |
 |
| |
| On simplification, v = -16.67 cm |
| |
 |
| |
 |
| |
| |
 |
| |
| Area enclosed by the image = (-2 cm)2 = 4cm2. |
