Virtual images and left–right flips
Teaching this? Open projector mode
A flat (plane) mirror forms a virtual image: it appears to sit behind the mirror, the same distance back as the object is in front, and the same size.
The image is laterally reversed — your raised right hand looks like the raised left hand of your reflection. Text reads backwards.
Check yourself
You stand 1 m in front of a plane mirror. How far from you does your image appear?
