What is the nature of the image formed by a concave lens for all real objects?

Last Updated: 25 Jun 2026

What is the nature of the image formed by a concave lens for all real objects? Here, the relevant answer is “Virtual erect diminished.” A sound solution relies on the governing concept rather than a memorised option letter, because option order may change in another paper. While reading a question, first note whether it asks for a definition, SI unit, formula, direction, cause, effect, or practical use.

AReal inverted magnified

BReal inverted diminished

CVirtual erect diminished

DVirtual erect magnified

Correct Answer: Virtual erect diminishedYour Answer: C

Explanation

— the scientifically appropriate response is Virtual erect diminished. Option-wise review: Virtual erect diminished is correct under the condition given in the stem. Real inverted magnified is incorrect because it describes a different quantity or phenomenon and does not meet the stated condition. Real inverted diminished is also incorrect; although it may be a valid physics term, its definition or application is not the one asked here. Virtual erect magnified is incorrect because it fails the governing relation or characteristic relevant to this case. Therefore, option C, Virtual erect diminished, is factually and logically consistent with the question. A concave lens always forms a virtual erect and diminished image for all positions of real objects.

Important Notes

Read the complete 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 Virtual erect diminished.
Physics answers are condition-dependent. The same lens, force, circuit, wave, or thermodynamic system can behave differently when distance, medium, temperature, direction, or boundary conditions change. Preserve every qualifier in the question.
Learn each concept as a five-part card: definition; common symbol; SI unit; principal equation; and one real-life application. This works for mechanics, heat, optics, sound, electricity, magnetism, and modern physics.
Use dimensional consistency as a quick check for formulas. Both sides of a valid physical equation must have the same dimensions. Units can eliminate distractors quickly, although a dimensionally correct option must still satisfy the actual law.

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.
