Which mirror is used in vehicle rear-view mirrors?

Last Updated: 25 Jun 2026

Here, the relevant answer is “Convex mirror.” A sound solution relies on the governing concept rather than a memorised option letter, because option order may change in another paper. The distractors in this question—Concave mirror, Plane mirror, Parabolic mirror—do not satisfy the exact condition stated. The final selection must agree with the explanation and marked answer: Convex mirror.

AConcave mirror

BPlane mirror

CConvex mirror

DParabolic mirror

Correct Answer: Convex mirrorYour Answer: C

Explanation

— the scientifically appropriate response is Convex mirror. Option-wise review: Convex mirror is correct under the condition given in the stem. Concave mirror is incorrect because it describes a different quantity or phenomenon and does not meet the stated condition. Plane mirror is also incorrect; although it may be a valid physics term, its definition or application is not the one asked here. Parabolic mirror is incorrect because it fails the governing relation or characteristic relevant to this case. Therefore, option C, Convex mirror, is factually and logically consistent with the question. Convex mirrors are used in rear-view mirrors as they give a wider field of view.

Important Notes

stem before looking at the options. Identify whether the demand is a definition, unit, formula, direction, cause, effect, image characteristic, or device principle. In this record, the confirmed answer is Convex mirror.
Eliminate Concave mirror, Plane mirror, Parabolic mirror here because none fulfils the exact requirement of the stem. The final answer and correct-index field must point to option C.
Exam memory point: connect Convex mirror directly with the key wording of the question, then verify it once against the relevant definition or formula before marking the answer.Convex mirror always forms diminished virtual image

FAQ

SSC CGL Physics FAQs

Common questions and clear answers for this topic.

How many physics questions usually appear in the SSC CGL exam?

Physics typically makes up a small portion of the General Science questions, usually focused on concepts rather than numerical problems.

Which physics topics are most important for SSC CGL?

Basic mechanics, heat, sound and light, and electricity and magnetism are the areas that come up most consistently across previous papers.

Do I need to solve numerical problems for SSC CGL physics?

Rarely. Most questions are conceptual and test everyday understanding rather than calculation skills.

Is NCERT physics enough for SSC CGL preparation?

NCERT textbooks from classes 9 and 10 build a strong enough conceptual base for most of what SSC CGL asks.

How can I make physics concepts easier to remember for SSC CGL?

Connecting concepts to everyday observations, like why a thermos keeps tea warm, makes them far easier to recall than memorizing definitions.
