Short, crisp and exam-focused revision notes covering the complete Class 10 Physics (Science) syllabus. Designed for fast, last-minute revision before CBSE Board exams — with all key concepts, definitions and formulas at your fingertips.

📘 What's Covered

• Light – Reflection & Refraction: Laws of reflection, spherical mirrors, mirror formula & magnification, refraction through glass slab, lens formula, refractive index, power of lens
• Human Eye & The Colourful World: Structure of the human eye, power of accommodation, defects of vision and their correction, dispersion of light through prism, atmospheric refraction, scattering of light (Tyndall effect)
• Electricity: Electric current & potential difference, Ohm's law, resistance & resistivity, series and parallel combinations, heating effect of current, electric power and energy, commercial unit of energy (kWh)
• Magnetic Effects of Electric Current: Magnetic field & field lines, right-hand thumb rule, magnetic field due to solenoid, force on current-carrying conductor, Fleming's left-hand rule, electric motor, electromagnetic induction, Fleming's right-hand rule, electric generator
• Sources of Energy: Renewable vs non-renewable sources, solar energy, wind energy, hydro energy, biogas, fossil fuels, nuclear energy — with advantages and limitations

⭐ Must-Memorise Formulas at One Place

• Mirror Formula: 1/v + 1/u = 1/f & Magnification m = -v/u
• Lens Formula: 1/v − 1/u = 1/f & Magnification m = v/u
• Power of Lens: P = 1/f (in metres), measured in dioptre (D)
• Ohm's Law: V = IR
• Resistance: R = ρl/A
• Series: R = R₁ + R₂ + R₃ | Parallel: 1/R = 1/R₁ + 1/R₂ + 1/R₃
• Electric Power: P = VI = I²R = V²/R
• Heating Effect: H = I²Rt
