13 Converging Diverging F F

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

15 Ray through center of lens no bending

17 Diverging Lens – smaller virtual image inside of F

18 Mirror & Lens Equations

19 = -- d o d i f d i POSITIVE for REAL image NEGATIVE for VIRTUAL image f POSITIVE for Concave Mirror CONVERGING lens NEGATIVE for Convex Mirror DIVERGING lens

20 S i - d i M = -- = -- S o d o M = magnification S i = size of image S o = size of object

21 beyond 2F between 2F & F inside of F

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

23 Object Location Image Location Image Type Image Size beyond 2F (C) between F & 2F (C) 2F (C) realsame between F & 2F (C) beyond 2F Fno image inside FBehind mirror; same side lens virtuallarger

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