Topics in Optics
Every topic of Optics, ordered by how many published questions sit behind it. A topic with none is listed rather than hidden — it is part of the chapter either way.
- Reflection of light and spherical mirrors
- Polarisation, Brewster's law and Polaroids
- Optical instruments - microscope and astronomical telescope
- Refraction at plane and spherical surfaces; thin lens and lens-maker's formula
- Total internal reflection and optical fibres
- Magnification, power of a lens and lenses in contact
- Refraction and dispersion through a prism
- Scattering of light - blue sky and red sunset
- Wavefront and Huygens' principle
- Interference and Young's double-slit experiment
- Diffraction at a single slit and the central maximum
Optics weightage in NEET-UG 2026 and JEE Main 2026
These shares are measured across many years of past papers, so they describe the long run rather than predicting any single paper.
| Paper | Share of Physics | Typical questions | Typical marks |
|---|---|---|---|
| NEET-UG 2026 chapter-wise weightage | 8.9% | 4.0 | 16 |
| JEE Main 2026 chapter-wise weightage | 8.9% | 2.2 | 8.9 |
Previous year questions from Optics
Past-paper questions are the most trustworthy material in the bank, and assembly reaches for them first when it builds a Optics test. They are not listed separately here, because a question's value is that you meet it under a clock rather than that you read it in a list.
A Optics test draws from all 537 published questions in this chapter, past papers first. Sit one now and see the per-topic breakdown.
