The following figure shows two images of an object that are at the focal point of two types of lenses. Identify lens types A and B.

• A- Convex lens, B- Concave lens

• A- Magnifying glass, B- Optical lens

• A- Concave lens, B- Convex lens

• A- Optical lens, B- Magnifying glass

Based on the diagram shown, identify what is meant by a focal point?

• A straight line passing through the optical center

• Point on principle axis

• Point at the centre of the lens.

• The distance between the focal point, F and the optical centre.

Which of the following is the position of an object to allow a convex lens to act as a magnifying lens?

• At the focal point F

• Same as focal length

• Between F and the optical center

• Farther than 2F
