What is the phenomenon when light is separated into its component colors?

Last Updated: 25 Jun 2026

What is the phenomenon when light is separated into its component colors? The most useful approach is to identify the physical quantity, phenomenon, law, or device named in the stem and connect it with its standard definition. Here, the relevant answer is “Dispersion.” A sound solution relies on the governing concept rather than a memorised option letter, because option order may change in another paper.

APolarization

BReflection

CDispersion

DAbsorption

Correct Answer: DispersionYour Answer: C

Explanation

— the scientifically appropriate response is Dispersion. Option-wise review: Dispersion is correct under the condition given in the stem. Polarization is incorrect because it describes a different quantity or phenomenon and does not meet the stated condition. Reflection is also incorrect; although it may be a valid physics term, its definition or application is not the one asked here. Absorption is incorrect because it fails the governing relation or characteristic relevant to this case. Therefore, option C, Dispersion, is factually and logically consistent with the question. Dispersion is the separation of white light into its constituent colors when it passes through a prism.

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 Dispersion.
Do not interchange closely related terms: mass and weight; distance and displacement; speed and velocity; heat and temperature; reflection and refraction; real and virtual image; current and potential difference; power and energy. Such pairs generate common SSC distractors.
Eliminate Polarization, Reflection, Absorption here because none fulfils the exact requirement of the stem. The final answer and correct-index field must point to option C.

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.
