Convex Lens Image Formation Quiz

Image Formation by Convex Lenses

• A convex lens forms a real and inverted image when the object is positioned far away.
• The image size decreases as the object moves further from the lens, nearing a point or minimum size when the object is at infinity.

Close Object Behavior

• When an object is very close to a convex lens, it produces a virtual and upright image.
• The magnification increases significantly when the object is near the lens, leading to a larger image relative to the object size.

Practical Applications

• Common items using a convex lens for image formation include:
  • Cameras
  • Magnifying glasses
  • Telescopes
  • Eyeglasses for correcting hyperopia (farsightedness)
