  • For a convex lens, the do is > 2f, describe the image
    It is a reduced and inverted image, and the di is at f
  • For a convex lens, the do = 2f, describe the image

    The image is the same size and inverted, and the di is at 2f
  • For a convex lens, the do is between f and 2f, describe the image
    the image is enlarged and inverted, the di is greater than 2f
  • For a convex lens, the do is before the f, describe the image
    The image is enlarged and upright, and the di is between f and 2f
  • For a convex lens, the do is at f, describe the image
    The image does not exist because the resulting light rays are all parallel
  • For a concave lens, describe the image regardless of position.
    The image is always virtual, but between the object and lens, it is always upright, and reduced
  • Correct farsightedness with convergent glasses
  • Correct nearsighted ness with divergent glasses
  • Image is only real if it is before the mirror or lens
  • For a concave mirror, the do is farther than f, describe the image
    di is positive and real, the image is inverted
  • For a concave mirror the do is at f, describe the image
    the di is at infinity, real, enlarged, and upright
  • For a concave mirror, the do is before f, describe the image
    The image is virtual, di < radius of mirror, upright, and enlarged
  • For a convex mirror, describe the image as it always is
    Virtual, upright, and reduced
