Questions and Answers

For an object placed between F and 2F of a concave mirror, the image formed is:

  • Virtual, upright, and same size as the object
  • Virtual, upright, and enlarged
  • Real, inverted, and enlarged (correct)
  • Real, inverted, and reduced

    • In a diverging lens, if a ray of light is parallel to the principal axis, it refracts as if it comes from:

  • Twice the focal length (2F)
  • The center of curvature (C)
  • The optical center of the lens
  • The focal point (F) (correct)

    • What type of image is formed by a plane mirror?

  • Virtual, upright, and same size as the object (correct)
