A convex mirror: 1. It always forms a virtual and erect image. 2. It always forms an enlarged image.

Single correct option

Consider the following statements about a convex mirror:
1. It always forms a virtual and erect image.
2. It always forms an enlarged image.
Which of the statements given above is/are correct?
  1. A. 1 only
  2. B. 2 only
  3. C. Both 1 and 2
  4. D. Neither 1 nor 2
Show answer and solution

Answer: (A) 1 only

A convex mirror forms a virtual, erect and diminished image for every position of a real object. Because the image is smaller, it covers a wider field of view, which is why it is used as a rear-view mirror. Statement 2 is wrong since the image is always diminished.
