Assertion (A): A convex mirror is used as a rear-view mirror in vehicles. Reason (R): A convex mirror always forms a virtual, erect, and diminished image, giving a wider field of view.
A. Both A and R are true and R is the correct explanation of A.
B. A is true but R is false.
C. A is false but R is true.
D. Both A and R are true but R is NOT the correct explanation of A.
Answer: Option A
Solution (By JKSSB Mock Tests)
Convex mirrors bulge outwards, which inherently provides a much wider field of view compared to plane mirrors. Regardless of the object's position, a convex mirror reliably produces virtual, erect, and diminished (smaller) images. This allows a driver to see a large area of the road behind them in a small mirror, making R the exact explanation for A.
