Practise conceptual reasoning on mirrors, refraction, total internal reflection, lenses, prism, optical instruments and sign conventions. Study sequence: Revise the Chapter 9 Complete Notes , practise the Important Questions , attempt the MCQs , Numericals and Case-Based Questions , then use this page to test whether you can distinguish a true statement from a valid explanation. Quick Answer — How do Assertion–Reason questions work? An Assertion–Reason question contains two statements: Assertion (A) and Reason (R). Judge each statement independently first, then decide whether R correctly explains A. The four-option format below follows the established CBSE Physics Assertion–Reason structure used in official sample papers. Current CBSE 2026–27 materials should always be tr...
