An object is placed in front of a convex mirror. Its image is formed:

  1. (A)at a distance equal to the object distance in front of the mirror.
  2. (B)at twice the distance of the object in front of the mirror.
  3. (C)half the distance of the object in front of the mirror.
  4. (D)behind the mirror and it's position varies according to the object distance.

Hints

Open one hint at a time and try again before the next.

Hint 1

Is the image formed by a convex mirror real or virtual?

Hint 2

Where do virtual images of a mirror lie?

Step-by-step solution

Each step shows the marks it earns, as an examiner would award them. Checked by an independent re-solve from the question paper.

  1. A convex mirror always forms a virtual, erect and diminished image behind the mirror, between the pole P and the focus F.

  2. As the object moves closer, the image moves from F towards P. Its position therefore depends on the object distance, so the answer is option (D).

    1 mark

Answer: Option (D)

Where the marks are

  • States the image is virtual, behind the mirror, and its position changes with object distance (1 mark)
