What is the NCERT Exemplar Class 10 Science Book?
The NCERT Exemplar Class 10 Science is an extra problem book published by NCERT, separate from your textbook. It carries tougher questions on the same chapters. For Chapter 9, it tests how well you understand light, reflection, and refraction through spherical mirrors, the mirror formula, magnification, refractive index, lenses, and ray diagrams.
- Made by NCERT: the level matches your CBSE Class 10 syllabus.
- Higher-order thinking: questions give you a ray diagram, an image size, or a focal length and ask you to reason.
- Free and official: the full PDF here is the real NCERT book, nothing added or removed.

What is Inside Chapter 9 of the NCERT Exemplar Class 10 Science
Chapter 9 of the Exemplar, Light - Reflection and Refraction, opens with multiple choice questions, then moves to short and long answer questions. Many are built around a ray diagram or a numerical on the mirror and lens formula, so you keep applying the mirror formula 1v + 1u = 1f with the correct sign convention. The table below shows the layout.
| Section | What it tests | Sample idea from Chapter 9 |
|---|---|---|
| Multiple Choice Questions | Quick concept checks with one correct option | Focal length of a concave mirror from object and image sizes |
| Short Answer Questions | Two to three line answers with a reason | Why a pencil in water looks bent at the surface |
| Long Answer Questions | Full answers with labelled ray diagrams | Image formation by a concave mirror for all object positions |
Across these sections you meet the big ideas: laws of reflection, spherical mirrors, the mirror formula, magnification, refraction, Snell's law, refractive index, lenses, the lens formula, and the power of a lens. Many questions also test the sign convention, the glass slab, and dioptre, all CBSE favourites.
Question Types in the NCERT Exemplar Class 10 Science Chapter 9
Knowing the question types helps you plan your practice. The Exemplar uses a few clear formats, and each trains a different skill you need for the CBSE board exam 2026-27.
- Single-correct MCQs: one option is right, such as the magnification of a rear-view mirror.
- Diagram-based MCQs: you read a ray diagram and pick the correct path through a glass slab or concave mirror.
- Numerical MCQs: you compute a value, such as the focal length of a concave mirror or the refractive index of a medium.
- Reasoning MCQs: you decide a condition, such as when a concave mirror forms an enlarged image.
- Short answer (SA): you write two to three lines with a reason, such as how refractive index links to the speed of light.
- Long answer (LA): you draw labelled ray diagrams, such as image formation by a concave mirror for every object position.
Why Solve the NCERT Exemplar for Chapter 9 Light - Reflection and Refraction
The textbook teaches the chapter; the Exemplar tests whether you can use it. Solving it for Light - Reflection and Refraction is one of the surest ways to lift your Science score.
- You apply the formulae cleanly. Knowing when a concave mirror gives a real, enlarged image and when it gives a virtual, magnified one is the single most-tested idea here.
- You master ray diagrams. Image formation by mirrors and lenses appears often, so neat labelled diagrams pay off in the exam.
- You handle refraction with confidence. Snell's law, refractive index, and the speed of light in a medium are CBSE favourites.
- You meet real-life examples. Rear-view mirrors, a torch bulb, and a pencil bent in water all appear.

How to Use the NCERT Exemplar Class 10 Science Chapter 9 PDF
The Exemplar works best as a practice book. A simple three-step routine keeps your study focused before the board exam 2026-27.
- Step 1, learn first. Finish the chapter in your textbook and the Notes page so you know the formulae, refractive index, and the power of a lens.
- Step 2, attempt on your own. Try the MCQs first, then short and long answers. Draw every ray diagram by hand.
- Step 3, check and fix. Open the Exemplar Solutions page, mark every wrong question, and redo it the next day.
Topics Covered in NCERT Exemplar Class 10 Science Chapter 9
Every question in this Exemplar chapter sits on a small set of core ideas. If you are clear on the points below, you can attempt the whole chapter. It also doubles as a quick revision checklist for 2026-27.
| Topic | What you must know |
|---|---|
| Laws of reflection | That the angle of incidence equals the angle of reflection, and the rule holds for all mirrors whatever their shape |
| Spherical mirrors | The pole, centre of curvature, focus, and focal length of concave and convex mirrors, and how image type changes with object position |
| Mirror formula and magnification | Using 1v + 1u = 1f and m = -vu = hiho with the New Cartesian sign convention |
| Refraction of light | Why light bends when it passes from one medium to another, and when it bends towards or away from the normal |
| Snell's law and refractive index | That n = sin isin r and that refractive index relates to the speed of light in the two media |
| Refraction through a glass slab | Why a ray entering a rectangular glass slab emerges parallel to itself, shifted sideways |
| Spherical lenses | Image formation by convex and concave lenses for all object positions, drawn with standard rays |
| Lens formula and power | Using 1v - 1u = 1f and the power P = 1f (in m) measured in dioptres |
Master these eight ideas and you can answer almost every Chapter 9 Exemplar question.
