Plane Mirror di=do

Plane Mirror

Type of Image Virtual Equal in Size Erect (Upright)

Spherical (Curved) Mirrors
Concave Convex

Concave Mirror(Converging)

Concave Mirror

Converging Mirror

Summary for Concave Mirror
When object is: Beyond C At C Between C and F At F Between F and mirror Image is: Between C and F At C Beyond C No image Virtual image

Mirror Equation 1 = 1 + 1 f do 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     +   converging (concave) mirrors f     -    diverging (convex) mirrors

Convex Mirror (Diverging)

Convex Mirror (Diverging)

Summary for Convex Mirror
Always: Virtual, reduced, upright image

Simulation

Problem Find the image distance, height and type for a 5cm object placed 60cm from a concave mirror of focal length of 18cm. Answer: di=25.7cm, hi=-2.14cm, Real, Inverted, Reduced
