Name four properties of the image formed by a plane mirror. 

Four properties of the image formed by a plane mirror:

1. Virtual Image: The image formed by a plane mirror is virtual, meaning it cannot be projected on a screen. It appears to be behind the mirror.
2. Upright: The image formed is always upright, meaning it has the same orientation as the object (not inverted).
3. Same Size as Object: The image has the same size as the object, meaning the magnification is 1 (no enlargement or reduction).
4. Laterally Inverted: The image is laterally inverted (or reversed). For example, if you raise your right hand, the image appears to raise its left hand.
