The image formed by a convex mirror is always real, inverted, and smaller in size. 3. When the object is placed at infinity and pole of the convex mirror, then the image is formed at the focus.

Consider the following statement 1. When the object is placed at infinity of the convex mirror, then the image is formed at the focus. 2. The image formed by a convex mirror is always real, inverted, and smaller in size. 3. When the object is placed at infinity and pole of the convex mirror, then the image is formed at the focus. Which of the following statements is CORRECT? Correct Answer Only 1

CONCEPT:

  • A convex mirror is a mirror whose reflecting surface is away from the center of the curvature.
  • A convex mirror is also known as a diverging mirror.


EXPLANATION:

  • When the object is placed at the infinity of the convex mirror, then the image is formed at the focus, behind the mirror and the nature of the image is erect, virtual, and highly diminished. Therefore, option 1 is correct.
  • The image formed by the convex mirror is always erect, virtual, and smaller in size (diminished). Therefore, option 2 is incorrect.
  • When the object is placed in between the infinity and pole of the convex mirror, then the image is formed between the focus and the pole, behind the mirror. Therefore, option 3 is incorrect.
