ffsshhttiikk What I do
- Analyze geometric optics and lens systems
- Model wave optics and interference patterns
- Calculate diffraction and grating spectra
- Design optical instruments (telescopes, microscopes)
- Study polarization and birefringence
- Analyze laser cavities and coherence
When to use me
When designing optical instruments, analyzing light behavior, or studying photonic devices.
Key Concepts
- Snell's Law: n₁sinθ₁ = n₂sinθ₂ for refraction at interfaces
- Thin Lens Equation: 1/f = 1/do + 1/di for image formation
- Interference: Path difference Δ = mλ for constructive/destructive
- Diffraction: sinθ = mλ/a for single slit, d sinθ = mλ for grating
- Malus's Law: I = I₀cos²θ for polarized light through analyzer
- Rayleigh Criterion: θ = 1.22λ/D for angular resolution
