Convex mirror is used as:
Rear view mirror in vehicles
The correct answer is Rear view mirror in vehicles.
The mirror formula, $\frac{1}{\text{f}} = \frac{1}{\text{v}} + \frac{1}{\text{u}}$, and the magnification formula, $\text{m} = -\frac{\text{v}}{\text{u}} = \frac{\text{Image Height}}{\text{Object Height}}$, apply to convex mirrors as well, with appropriate sign conventions. For a convex mirror, the focal length 'f' is considered negative, and for real objects placed in front, the object distance 'u' is negative. The image distance 'v' is always positive (image behind the mirror), resulting in a positive magnification 'm' (erect image) and |m| < 1 (diminished image).
