Type of Image • Virtual • Equal in Size • Erect (Upright)
Spherical (Curved) Mirrors • Concave • Convex

Summary for Concave Mirror When object is: • Beyond C Image is: • Between C and F • At C • Between C and F • Beyond C • At F • No image • Between F and mirror • Virtual image
Mirror Equation 1=1+1 f d o di
Magnification M= hi = -di ho do
Sign Convention do + object is in front of the mirror di + real image, in front of the mirror di - virtual image, behind the mirror hi + erect image hi - inverted image f f + converging (concave) mirrors - diverging (convex) mirrors

Convex Mirror (Diverging)
Summary for Convex Mirror Always: • Virtual, reduced, upright image
