How will the NCERT Exemplar Class 12 Physics on Collegedunia Help You?
This page hosts the official 2026-27 print and adds the practice-strategy layer that a raw Exemplar PDF lacks.
- 2026-27 NCERT Alignment: Every problem in the 32-question set is mapped to a sub-topic that still belongs to the current Class 12 Physics syllabus, so you do not waste time on dropped content.
- Question-Type Inventory: A clear count of MCQ-I, MCQ-II, VSA, SA, and LA problems lets you pace each sitting against the actual size of the load.
- Self-Test Format: The book prints only the problems, so you can attempt cold, mark your weak ones, and return to them in the final revision week.
- JEE and NEET Crossover: Recent JEE Main and NEET sittings have reused Exemplar setups almost verbatim. Working this NCERT Exemplar Class 12 Physics is the cheapest way to lift your entrance-exam Physics score for Electromagnetic Waves.

What's Inside the NCERT Exemplar Class 12 Physics
The Exemplar runs about 7 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 |
|---|---|
| Maxwell's displacement current and Ampere-Maxwell law | 8.1, 8.7, 8.14, 8.22 |
| Properties of electromagnetic waves | 8.2, 8.8, 8.15, 8.19, 8.24 |
| Energy density and intensity of EM waves | 8.3, 8.9, 8.20, 8.25, 8.30 |
| Electromagnetic spectrum and applications | 8.4, 8.5, 8.10, 8.11, 8.16, 8.17, 8.18, 8.26, 8.27 |
| Radiation pressure and momentum of EM waves | 8.6, 8.12, 8.13, 8.21, 8.28, 8.29, 8.31, 8.32 |
Electromagnetic Waves NCERT Exemplar Question-Type Breakdown
The 2026-27 Exemplar print divides Chapter 8 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) | 7 | 1 |
| MCQ-II (one or more correct) | 6 | 2 |
| Very Short Answer (VSA) | 7 | 1 to 2 |
| Short Answer (SA) | 7 | 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 Electromagnetic Waves 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.

Topper Strategy for the Electromagnetic Waves Exemplar
CBSE Class 12 Physics Boards 2024 and 2025 toppers consistently cite three habits when they describe how they used the Exemplar for this chapter. The pattern is similar across schools and coaching centres.
- Two passes, not one: Solve every Exemplar problem in the first pass. In the second pass, attempt only the starred (wrong-first-time) problems. The second pass is where score actually moves.
- Write LA answers in board format: Diagram, given / to-find, formula statement, substitution, final answer in a box. The Exemplar's LA problems are tuned for exactly this layout, so practising it on the Exemplar earns easy 5-mark wins on the board paper.
- Compare your answer with the official Exemplar Solutions: Do not invent your own marking scheme. The Exemplar Solutions resource carries the official step-by-step credit map for each problem.
How to Use the Electromagnetic Waves Exemplar PDF Alongside the NCERT Textbook
The Exemplar is the next layer on top of the NCERT chapter, not a replacement for it.
- Finish the NCERT chapter first: Work every intext example and all back-exercises before opening the Exemplar.
- Attempt MCQ-I and MCQ-II in one sitting: Use only your formula sheet. Time-box to 60 minutes.
- Mark every wrong attempt with a star: Return to starred problems in the week before boards. This second pass is where scores actually move.
Electromagnetic Waves 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 |
|---|---|
| Speed of light in vacuum | c = 1 / sqrtmu0 epsilon0 |
| Energy density of EM waves | u = (1 / 2) epsilon_0 E_0 squared |
| Intensity in terms of E_0 | I = (1 / 2) epsilon_0 c E_0 squared |
| Maxwell's displacement current | I_d = epsilon_0 d phi_E / d t |

Electromagnetic Waves CBSE Marks Weightage Compared Across Class 12 Physics Chapters
The visual below maps the typical CBSE Class 12 Physics marks distribution across all 14 chapters of the NCERT book, averaged over the last five board papers. This is the same canonical table used by every Electromagnetic Waves Collegedunia resource page, so the numbers match the bullets at the top of this article.
Student Feedback
"The sub-topic table showed me which Exemplar problems to tackle first. I went straight to energy density and intensity because that is where the 5-mark LA usually comes from." - Arjun, Class 12 CBSE 2025
"I used to skip MCQ-II thinking it was like MCQ-I. Once I slowed down and treated each option separately, my score in Chapter 8 jumped." - Priya, JEE Main 2025 aspirant

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 8 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 8 Exemplar Book PDF?
Ans. The NCERT Exemplar Class 12 Physics Exemplar PDF runs approximately 7 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 8 of the Class 12 Physics Exemplar holds 32 problems in total, split as MCQ-I (7), MCQ-II (6), VSA (7), SA (7), 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 Electromagnetic Waves Exemplar problems?
Ans. solved answers for every problem in this chapter are on the Electromagnetic Waves Class 12 Physics NCERT Exemplar Solutions page.
Ques. How long does it take to finish Chapter 8 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 8. NEET also reuses Exemplar MCQ-II patterns. Use the NCERT Exemplar Class 12 Physics during your year, then revisit before the entrance.
