A real question from the course. No sign-up needed.

From the chapter: Light: Mirrors, Lenses and the Human Eye

Which mirror is fitted as a rear-view mirror in vehicles, and for what reason?

Show the answer and why

Answer: A.

A convex mirror gives an erect, diminished virtual image for any real object, and the diminished image lets a large area fit in a small mirror. A concave mirror gives a magnified image only at close range and an inverted real image for far objects, so it is not suitable; a plane mirror gives a virtual, not real, image and a narrow field.
