What's Inside the NCERT Exemplar Class 12 Physics
The Exemplar runs about 8 pages and packs the problems into five fixed sections. The topic map below tells you where each sub-topic is concentrated, so you can target your weakest area without scanning the whole chapter.
| Sub-Topic Concentration | Problem Numbers |
|---|---|
| Reflection at plane and spherical mirrors | 9.1, 9.2, 9.12, 9.17, 9.22 |
| Refraction at plane and spherical surfaces | 9.3, 9.4, 9.5, 9.13, 9.18, 9.23, 9.28 |
| Thin lens, lensmaker formula, lens combinations | 9.6, 9.7, 9.14, 9.19, 9.24, 9.29 |
| Prism, dispersion, total internal reflection | 9.8, 9.9, 9.15, 9.20, 9.25, 9.30 |
| Optical instruments (microscope, telescope) | 9.10, 9.11, 9.16, 9.21, 9.26, 9.27, 9.31, 9.32 |
Ray Optics and Optical Instruments NCERT Exemplar Question-Type Breakdown
The 2026-27 Exemplar print divides Chapter 9 into five question types. The split below tells you how many of each kind you face and the indicative mark value used in the Exemplar's own marking scheme.
| Question Type | Number of Problems | Indicative Marks Each |
|---|---|---|
| MCQ-I (single correct) | 11 | 1 |
| MCQ-II (one or more correct) | 5 | 2 |
| Very Short Answer (VSA) | 5 | 1 to 2 |
| Short Answer (SA) | 6 | 3 |
| Long Answer (LA) | 5 | 5 |
| Total | 32 | - |
MCQ-II is the most-failed type because at least one option besides the obvious one is correct; treat it as a slow type, not a quick one.
2026-27 Syllabus Status of Ray Optics and Optical Instruments Exemplar Problems
The NCERT Exemplar publication was not rationalised when the NCERT Exemplar Class 12 Physics was trimmed in 2023. Some Exemplar problems still touch sub-topics that are no longer part of the current Class 12 Physics chapter. Skip those during board preparation; keep them only if you are working the book for JEE Main or NEET, where the entire scope still matters.
Detailed kept-trimmed-removed table: see the breakdown on the Ray Optics and Optical Instruments Class 12 Physics NCERT Book PDF page.
Why the NCERT Exemplar Matters for JEE Main and NEET Ray Optics and Optical Instruments Prep
The NCERT Exemplar is the official NCERT publication that paper-setters reference when they design HOTS problems for both the CBSE Board and the JEE Main / NEET papers. Three reasons it deserves a slot in your study plan:
- Same author body: The committees that write NCERT textbook and NCERT Exemplar overlap. Practising the Exemplar trains you on the exact phrasing CBSE markers expect.
- Five question types: Few other resources cover MCQ-I, MCQ-II, VSA, SA, and LA in one book. The mix matches today's CBSE paper structure and the JEE Main MCQ-II / multiple-correct trap-style.
- Free and offline: The PDF works on a phone with no reader app. Print only the section you need (the LA pages, for instance) without buying a private question bank.
Boards toppers consistently cite the Exemplar as the single book that lifted their score from a B1 to an A1 in Physics.
Ray Optics and Optical Instruments Exemplar vs NCERT Textbook: Difficulty Step-Up
The Exemplar takes the same physics setup as the NCERT textbook chapter but adds one or two complicating layers. The contrast below shows what changes between the two books.
| Aspect | NCERT Textbook | NCERT Exemplar |
|---|---|---|
| Purpose | Concept building and solved examples | HOTS practice with multi-step problems |
| Difficulty band | Easy to medium | Medium to very hard (especially LA) |
| Solved examples in chapter | Around 6 to 14 solved examples | Zero step-by-step solutions in the book |
| Total practice problems | Roughly 10 end-of-chapter Exercises | 32 problems across 5 types |
| Match rate with JEE / NEET | Low to medium | High (around 25 to 30% reused) |
If you can finish only one extra book outside the NCERT textbook for Ray Optics and Optical Instruments, make it the Exemplar.
JEE Main and NEET Ray Optics and Optical Instruments Questions Inspired by the Exemplar
Recent entrance papers reused the setup of several Exemplar problems from this chapter. The instances below come from the last two sittings of JEE Main and NEET.

Ray Optics and Optical Instruments Top Formulae to Memorise Before Attempting the Exemplar
Most Exemplar problems hinge on a small set of recurring formulas. Lock these four into memory before opening the NCERT Exemplar Class 12 Physics; you will save 30 to 40% of attempt time per problem.
| Concept | Formula |
|---|---|
| Mirror formula | 1 / v + 1 / u = 1 / f |
| Lens formula | 1 / v - 1 / u = 1 / f |
| Lensmaker formula | 1 / f = (n - 1)(1 / R1 - 1 / R2) |
| Prism deviation (minimum) | n = sin(A + Dm/2) / sin(A/2) |

NCERT Exemplar Class 12 Physics - Frequently Asked Questions
Ques. Where can I download the NCERT Exemplar Class 12 Physics for free?
Ans. You can download the NCERT Exemplar Class 12 Physics directly from this page. Both the Normal and HD versions are available, and both are free.
Ques. Is the Exemplar Book PDF aligned with the 2026-27 NCERT?
Ans. The NCERT Exemplar publication was not rationalised when the NCERT Exemplar Class 12 Physics was trimmed. The bulk of Chapter 9 problems still map to the current 2026-27 textbook chapter; a small minority touch sub-topics that were removed and can be skipped during board preparation.
Ques. How many pages is the Class 12th Physics Chapter 9 Exemplar Book PDF?
Ans. The NCERT Exemplar Class 12 Physics Exemplar PDF runs approximately 8 pages and packs 32 HOTS problems across MCQ-I, MCQ-II, VSA, SA, and LA types.
Ques. Is this NCERT Exemplar Class 12 Physics aligned with the 2026-27 CBSE syllabus?
Ans. Chapter 9 of the Class 12 Physics Exemplar holds 32 problems in total, split as MCQ-I (11), MCQ-II (5), VSA (5), SA (6), and LA (5).
Ques. Are Exemplar problems compulsory for the CBSE Class 12 board exam?
Ans. Exemplar problems are not part of the prescribed NCERT textbook chapter, but CBSE has used Exemplar-style HOTS items in 4 of the last 5 board papers. For an A1 grade in Physics, working the Exemplar is practically required.
Ques. Where can I find the solutions to the Ray Optics and Optical Instruments Exemplar problems?
Ans. solved answers for every problem in this chapter are on the Ray Optics and Optical Instruments Class 12 Physics NCERT Exemplar Solutions page.
Ques. How long does it take to finish Chapter 9 of the Exemplar Book?
Ans. Plan for around 10 to 14 hours spread across four to five sittings: one hour for the MCQ types, two to three hours for VSA and SA, and the rest for the LA section. Always revisit any wrong attempts the same day to lock in the correction.
Ques. Can I use the Exemplar Book for JEE Main and NEET preparation?
Ans. Yes. JEE Main 2024 and 2025 each carried at least one question whose setup mirrored an Exemplar problem from Chapter 9. NEET also reuses Exemplar MCQ-II patterns. Use the NCERT Exemplar Class 12 Physics during your year, then revisit before the entrance.
