1. Ray Optics
- Reflection of Light:
- Laws of Reflection: Angle of incidence = Angle of reflection.
- Plane Mirror: Image formation and characteristics (virtual, same size as object, etc.).
- Spherical Mirrors: Concave and convex mirrors, mirror formula (1/f = 1/v + 1/u), and magnification. Best IIT-JEE ,NEET Coaching In Varanasi.
- Refraction of Light:
- Laws of Refraction: Snell’s law (n1 sin θ1 = n2 sin θ2).
- Refractive Index: Measure of how much light bends when entering a medium.
- Total Internal Reflection: Condition and applications (e.g., fiber optics). Best IIT-JEE ,NEET Coaching In Varanasi.
- Lenses:
- Types of Lenses: Convex (converging) and concave (diverging).
- Lens Formula: 1/f = 1/v – 1/u and magnification.
- Lens Maker’s Formula: 1/f = (n – 1) [ (1/R1) – (1/R2) ]. Best IIT-JEE ,NEET Coaching In Varanasi.
- Optical Instruments:
- Microscope: Structure, working, and magnifying power.
- Telescope: Structure, working, and magnifying power. Best IIT-JEE ,NEET Coaching In Varanasi.
2. Wave Optics
- Interference:
- Young’s Double Slit Experiment: Understanding of fringes, path difference, and conditions for constructive and destructive interference.
- Coherent Sources: Definition and requirement for interference. Best IIT-JEE ,NEET Coaching In Varanasi.
- Diffraction:
- Single-Slit Diffraction: Central maximum and secondary maxima.

3. Optical Phenomena
- Dispersion of Light: Separation of light into its constituent colors (rainbow formation).
- Scattering of Light: Tyndall effect, Rayleigh scattering, and its significance in the color of the sky. Best IIT-JEE ,NEET Coaching In Varanasi.
Key Formulas:
- Mirror Formula: 1/f = 1/v + 1/u
- Lens Formula: 1/f = 1/v – 1/u
- Magnification (Mirror and Lens): M = v/u
