Question

The magnification produced by a spherical mirror is \( -2.0 \). The mirror used and the nature of the image formed will be:

• A. Convex and virtual
• B. Concave and real
• C. Concave and virtual
• D. Convex and real

Hint:

A negative magnification in a mirror always means the image is real and inverted. Only a concave mirror can form such an image.

Answer 1

The Correct Option is B

The magnification \( m \) produced by a mirror is \( m = \frac{-v}{u} \). For spherical mirrors: - A negative magnification signifies a real, inverted image. - A concave mirror forms a real, inverted image when the object is positioned beyond the focal point. - A magnification with an absolute value greater than 1 (e.g., 2.0) indicates a magnified image, larger than the object. - A convex mirror exclusively produces virtual, diminished, and upright images, never real ones. Consequently, the mirror is concave, and the image formed is real and magnified. Final answer: Concave and real
