Science (086) — AI-generated practice question

A convex mirror is more suitable as a rear-view mirror.

Reasons:

1. A convex mirror always forms a virtual, erect, and diminished image, regardless of the object's position.
2. It has a wider field of view because its reflecting surface is curved outwards, allowing the driver to see a much larger area of traffic behind.
3. The image is always formed behind the mirror between P and F, making it safe and convenient to view.

Thus, a convex mirror enables the driver to see more area in a single glance, ensuring safer driving.

Examiners expect two clear reasons: (1) erect and diminished image and (2) wider field of view. Simply naming the mirror without reasons will cost marks. The phrase "wider field of view" is the key technical term from the textbook — always use it. Do not confuse with concave mirror; concave gives magnified/inverted images for most object positions, making it unsuitable here.
