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 given by: \[ m = \frac{-v}{u} \] In the case of spherical mirrors: - Negative magnification means the image is real and inverted.
- A concave mirror can produce a real, inverted image when the object is placed beyond the focal point.
- The magnification being greater than 1 in magnitude (i.e., 2.0) means the image is larger than the object.
- A convex mirror always forms a virtual, diminished, and upright image, never real.
Therefore, the mirror is concave, and the image formed is real and magnified. Final answer: Concave and real
