How to locate the image in a plane mirror fast and error-free.
What we do
Object vs image; sign/angle conventions (measure w.r.t. normal)
Position rule: image distance = object distance (behind the mirror)
Size & magnification:
𝑚 =+1
m=+1 (same size), upright; lateral inversion
Fast constructions for point and extended objects
Short problems: distance between object & image, shift when object moves, multiple points on a stick
