Question : A rearview mirror for driving is:
Option 1: plain
Option 2: concave
Option 3: convex
Option 4: inverted
Correct Answer: convex
Solution : The correct answer is convex.
We use the convex type of mirrors as a rearview mirror in vehicles because convex mirrors always form virtual, erect and diminished images and provide for a larger field of view than normal mirrors. Convex mirrors provide a much wider angle of view when used in vehicles as a rearview mirror.
