Geometric Optics: Reflection and Refraction
2-3 weeksStudy the law of reflection, Snell's law of refraction, critical angle, total internal reflection, and how light behaves at plane and curved surfaces.
Lenses, Mirrors, and Optical Instruments
2-3 weeksLearn the thin lens equation, mirror equation, magnification, and ray tracing. Apply these to design cameras, microscopes, telescopes, and corrective eyeglasses.
Wave Optics: Interference and Diffraction
2-3 weeksExplore Young's double-slit experiment, single-slit diffraction, diffraction gratings, thin-film interference, and the conditions for constructive and destructive interference.
Polarization and Scattering
1-2 weeksStudy polarization methods (filters, reflection, scattering), Brewster's angle, Malus's law, and Rayleigh scattering. Understand applications in sunglasses, LCD screens, and atmospheric optics.
Modern and Quantum Optics
2-3 weeksInvestigate the photoelectric effect, photon model, wave-particle duality, stimulated emission, laser operation, and the fundamentals of quantum optics.
Applied Optics and Photonics
2-3 weeksStudy fiber optics, holography, spectroscopy, optical coatings, adaptive optics, and the role of optics in telecommunications, medicine, and manufacturing.
Advanced Topics and Emerging Frontiers
2-4 weeksExplore metamaterials, negative refraction, nonlinear optics, ultrafast optics, quantum entanglement of photons, and photonic computing.
