Class 10 Physics Syllabus: What Changed?

The current Class 10 Physics syllabus has 4 chapters instead of the earlier 5.

A guide that still has Sources of Energy follows the old syllabus. Check the CBSE Class 10 syllabus for unit-wise marks.

Class 10 Physics Chapters: What Each Chapter Covers

Chapter 9 — Light – Reflection and Refraction

The longest Physics chapter covers reflection by spherical mirrors, image formation, sign convention, the mirror formula and magnification, then refraction through a glass slab, refractive index, lenses, ray diagrams, the lens formula and the power of a lens.

Key formulae: 1/v + 1/u = 1/f (mirror), 1/v − 1/u = 1/f (lens), m = h′/h, P = 1/f.

Chapter 10 — The Human Eye and the Colourful World

This chapter explains how the eye works, the power of accommodation, and the defects myopia, hypermetropia and presbyopia with their correction. It then covers refraction through a prism, dispersion, atmospheric refraction (twinkling of stars, early sunrise) and scattering of light, including the Tyndall effect and the blue sky.

See eSaral's notes on the Human Eye and Colourful World.

Chapter 11 — Electricity

This chapter covers electric current, potential difference, circuit diagrams and Ohm's law. Students learn the factors that affect resistance, resistivity, resistors in series and parallel, the heating effect of current (Joule's law) and electric power.

Key formulae: V = IR, R = ρl/A, R = R₁ + R₂ (series), 1/R = 1/R₁ + 1/R₂ (parallel), H = I²Rt, P = VI.

Practise numericals with the Electricity Class 10 NCERT notes.

Chapter 12 — Magnetic Effects of Electric Current

The last Physics chapter covers magnetic field lines, the field due to a current in a straight wire, a circular loop and a solenoid, the right-hand thumb rule, and the force on a current-carrying conductor (Fleming's left-hand rule). It ends with domestic electric circuits, earthing and fuses.

How to Study Class 10 Physics from NCERT

• Draw ray diagrams daily. Chapters 9 and 10 depend on clean, labelled ray diagrams.
• Keep one Class 10 Physics formula sheet with SI units for all four chapters.
• Solve every in-text and exercise numerical in the Electricity and Light chapters.
• Check your answers with NCERT Solutions for Class 10 Science, then practise the NCERT Exemplar for Class 10 Science.
• Test yourself in eSaral's Class 9 and 10 test series.

💡 Expert Tip by eSaral Physics Faculty In Class 10 Physics, most lost marks come from sign convention errors in mirror and lens numericals. Write the sign of u, v and f before substituting, every time.
