Question

The image formed by a concave mirror is observed to be virtual, erect, and larger than the object. Where should be the position of the object?

• A. Between the principal focus and the center of curvature
• B. At the center of curvature
• C. Beyond the center of curvature
• D. Between the pole of the mirror and its principal focus.

Answer 1

The correct option is D

Between the pole of the mirror and its principal focus.

Concave Mirror:

1. If a hollow sphere is cut into parts and the outer surface of each cut part is painted, it becomes a mirror, with the inner surface reflecting light.

The explanation for the Correct answer:

Option D: Between the pole of the mirror and its principal focus.

1. When an object is placed between the pole of the mirror and its principal focus, the image formed by a concave mirror appears virtual, erect, and larger than the object.
2. Hence, option D is correct.

The explanation for Incorrect answer(s):

Option A: Between the principal focus and the center of curvature.

1. A concave mirror produces a virtual, erect, and enlarged image when an object is placed between the mirror's principal focus and center of curvature.
2. Hence, option A is not correct.

Option B: At the center of curvature.

1. If an object is placed in the center of a concave mirror's curvature, the image formed will be the same size.
2. Hence, option B is not correct.

Option C: Beyond the center of curvature.

1. If an object is placed beyond the center of curvature of a concave mirror, the image formed will be inverted and reduced in size.
2. Hence, option C is not correct.

Thus, option D is the correct answer.
