Properties of Curved Mirrors and Lenses

Concave Mirror

Convex Mirror

LENSES

Converging Diverging F F

CONVERGING LENS Ray parallel to axis through F Ray through F parallel to axis

Ray through center of lens
no bending

Diverging Lens – smaller virtual image inside of F

Mirror & Lens Equations

= -- do di f di POSITIVE for REAL image NEGATIVE for VIRTUAL image f POSITIVE for Concave Mirror CONVERGING lens NEGATIVE for Convex Mirror DIVERGING lens

Si di M = -- = -- So do M = magnification Si = size of image So = size of object

beyond 2F @ F @ 2F inside of F between 2F & F

Concave Mirror & Converging Lens
Object Location Image Location Image Type Image Size beyond 2F (C) @ 2F (C) between F & 2F (C) @ F inside F

Object Location Image Location Image Type Image Size beyond 2F (C) between F & 2F (C) real smaller @ 2F (C) same larger @ F no image inside F Behind mirror; same side lens virtual

Convex Mirror; Diverging Lens
any location virtual image, smaller Plane Mirror any location virtual image, same size
