10th class Physics

Physics for Class 10 focuses on foundational concepts that explain natural phenomena and the principles governing the physical world. It combines theoretical knowledge with practical applications and is divided into several key topics:

1. Light: Reflection and Refraction

•Reflection of Light: Laws of reflection, types of mirrors (plane and spherical), and image formation by mirrors.

•Refraction of Light: Laws of refraction, refractive index, refraction through lenses (convex and concave), and lens formulas.

2. Human Eye and the Colourful World

•Structure and functioning of the human eye.

•Defects of vision (myopia, hypermetropia, and astigmatism) and their correction.

•Dispersion of light through a prism and phenomena like scattering of light (blue sky and red sunsets).

3. Electricity

•Electric current: Circuit diagrams, Ohm’s law, resistors in series and parallel.

•Electrical Power and Energy: Heating effect of current and power formulas.

•Household circuits and safety measures.

4. Magnetic Effects of Electric Current

•Magnetic fields around a current-carrying conductor.

•Electromagnetic induction, Fleming’s Left-Hand and Right-Hand Rules.

•Domestic electric circuits and circuit breakers.

5. Sources of Energy

•Conventional and non-conventional sources of energy.

•Renewable energy resources: Solar, wind, geothermal, and hydropower.

•Environmental impact and sustainable energy use.

6. The Universe

•Basic understanding of stars, planets, and the solar system.

•Concept of satellites and artificial satellites.

7. Effects of Current (Electromagnetism)

•Uses and working principles of electric motors and generators.
