 Focal Length + or -? + converging lens or mirror - diverging lens or mirror Object Distance + or -? + if left of lens - if right of lens Image Distance + or -? + real - virtual Plane Mirror Image? always U V and same size at distance I = -O Diverging Lenses/Mirrors everything is smaller, upright, virtual and within the focal length. UVS WNF DiVex Mirror DAve Lens Magnification h'/h or s'/s (relative to height or distance) Converging Mirrors/Lenses As you move the object further away, the image gets closer to the focal point and smaller. As you move it closer, the opposite happens. For Lenses remember: Real and Virtual sides are flipped & convex and concave are reversed Formation of Real Image using a Converging Lens only occurs if object is outside of the focal length Converging Scenario: If object beyond R... image forms between R and f. Converging Scenario: If object at R... image will form at R. Converging Scenario: If object between R and f... image will form beyond R. Converging Scenario: If object at f... no image. Converging Scenario: If object within f... image is larger, upright, virtual. Ultimate Formula i = (o x f) / (o - f) TBR Ex 10.9a An object is moved from w/n the focal length of a converging lens to a distance beyond the focal length. Image of the object is observed to change from: UV to IR. For a single lens or mirror, upright images are always ___ and inverted images are always ___. Virtual & Real 3 Common Lens Aberrations Spherical, Astigmatic, Chromatic
