14 True/False questions

  1. focal lengthpoint where incident light rays that are parallel to the principal axis converge after reflecting from a mirror or refracting through a lens

          

  2. concave mirrorthe edges curved away from the observer that reflects light from its outwardly curving surface; produces an upright, reduced, virtual image

          

  3. focal pointdistance between the focal point and the mirror or lens

          

  4. plane mirrorreflects light from its inwardly curving surface, the edges of which curve toward the observer; can produce either an upright, virtual image or an inverted, real image

          

  5. convex mirrorreflects light from its inwardly curving surface, the edges of which curve toward the observer; can produce either an upright, virtual image or an inverted, real image

          

  6. real imageoptical image that is formed by the converging of light rays

          

  7. imageoptical image that is formed by the converging of light rays

          

  8. spherical aberrationimage defect of a spherical mirror or lens that does not allow parallel light rays far from the principal axis to converge at the focal point and produces an image that is fuzzy, not sharp

          

  9. principal axisstraight line perpendicular to the surface of a mirror or lens that divides the mirror or lens in half

          

  10. objectluminous or illuminated source of light rays

          

  11. virtual imageoptical image that is formed by the converging of light rays

          

  12. specular reflectiona scattered, fuzzy reflection produced by a rough surface

          

  13. magnificationoptical reproduction of an object formed by the combination of light rays reflected or refracted by an optical device

          

  14. diffuse reflectiona scattered, fuzzy reflection produced by a rough surface
