What phenomenon is evident in lenses? https://wiki.brown.edu/confluence/display/PhysicsLabs/PHYS+0080+BC
Basic Types of Lenses • Convex • Concave
Convex Lens http://www.shokabo.co.jp/sp_e/optical/labo/lens/lens.htm
Concave Lens http://www.shokabo.co.jp/sp_e/optical/labo/lens/lens.htm
Type of Image • Real or Virtual • Enlarged or Reduced • Erect or Inverted
Convex Lens f C Center

Rules for Ray Diagrams for Convex Lens • A parallel ray refracts through the focal point. • A ray through the center of the lens continues straight. • A ray coming through the focal point, refracts parallel to the principal axis.

When the object is: Beyond 2F At 2F Between 2F and F At F Between F and lens Then the image is: Between 2F and F At 2F Beyond 2F No image Virtual image Summary for Convex Lens
Sign Convention do + object distance di + real image, other side of lens di - virtual image, same side as object hi + erect image hi - inverted image f + converging lens (convex) f - diverging lens (concave)
Magnification M = hi = -di ho do Note: When magnification is <0, the image is inverted.
Lens Equation 1 = 1 + 1 f do di
Concave Lens Object Image
Summary for Concave Lens Always: • Virtual, reduced, upright image
