A plane mirror produces an image that is:
- AReal, inverted and larger than the object.
- BReal, upright and same size as the object.
- CReal upright and smaller than the object.
- DVirtual, upright and the same size of the object.
A plane mirror produces an image that is:
Explanation:
So a plane mirror always forms a virtual, upright and same sized image.
