Convex Mirror — Rear ViewEasyQuestion 20204
Question
Convex mirrors are used as rear-view mirrors in vehicles because:
- AThey form magnified images
- BThey form real images always
- CThey provide a wider field of view and always erect imagesCorrect
- DThey have larger focal lengths than concave mirrors
Correct answer
They provide a wider field of view and always erect images
Explanation
Convex mirrors diverge reflected rays, giving a wider field of view. All images are virtual, erect, and diminished — allowing the driver to see a wider region behind. The diminished size means everything appears farther than it is (hence the warning).
