Correct option is B
Correct Answer: B
Explanation
- Magnification (m) produced by a spherical mirror is defined as the ratio of the height of the image (h') to the height of the object (h).
- It expresses the degree to which an object is enlarged or diminished in its image relative to the object's actual size.
- Mathematically, it is represented as:

- Magnification is also related to the object distance (u) and image distance (v) by the formula:
- Sign Convention: For a real image, $m is negative because the image is inverted (h' is negative). For a virtual image, m is positive because the image is erect (h' is positive).
- If |m| > 1, the image is enlarged; if |m| < 1, th image is diminished; if |m| = 1, the image is the same size as the object.
- Magnification is a unitless quantity since it is a ratio of two similar dimensions (heights or distances).
