Physics - Geometrical Optics Question with Solution | TestHub

When an object is placed in front of a plane mirror, object distance is equal to the image distance. In the first case, the image distance will be $12 \mathrm{cm}$ from the mirror. In the next case, as the mirror is moved towards the object, the object distance becomes $8 \mathrm{cm}$. Hence, image distance will also be $8 \mathrm{cm}$.
