Worked practice questions

For a concave mirror, as an object moves from infinity towards the focus, the real image

  1. remains virtual throughout
  2. stays fixed at the centre of curvature
  3. moves from F towards infinity, growing larger
  4. moves from F towards the pole, shrinking
Show answer and solution

Correct answer: C. moves from F towards infinity, growing larger

Object at infinity → image at F (tiny). As the object approaches F, the real image recedes from F towards infinity and grows. At F the image is at infinity; inside F it becomes virtual.
