Alrik the Garden Gnome is 2.1 cm tall and placed 40 cm in front of a convex lens with a focal length of 16 cm.

a) Where is the image of Alrik formed?

  • on the opposite side of the lens
  • on the same side as the lens
  • no image is formed

b) What is the image distance from the lens?

si = cm

c) What is the height of the image?

hi = cm

d) What is the magnification?

m =

e) The image is

  • real
  • virtual

f) If Alrik is moved a small amout farther from the lens, the image will

  • move closer to the lens and shrink in size
  • move further from the lens and shrink in size
  • mover further from the lens and grow in size
  • move closer to the lens and grow in size
