Scope and structure (typical contents and chapter flow)

1. Fundamentals & Geometrical Optics

   • Nature of light; rectilinear propagation; reflection and refraction.
   • Laws of reflection/refraction; refractive index; Snell’s law derivations.
   • Gaussian optics: paraxial approximations, cardinal points, principal planes.
   • Image formation by spheres, lenses; matrix methods for optical systems.

2. Wave Optics / Physical Optics

   • Wave equation for light; Huygens’ principle and its applications.
   • Superposition principle; coherence (temporal and spatial), coherence length/time.
   • Interference: Young’s double-slit, thin film interference, Newton’s rings, Michelson interferometer—derivations, fringe formulas, resolving power considerations.

3. Diffraction

   • Fresnel and Fraunhofer diffraction regimes; mathematical treatments.
   • Single-slit and multiple-slit (grating) diffraction; diffraction integrals and approximations.
   • Aperture diffraction, resolving power, Rayleigh criterion.

4. Polarization

   • Polarization states (linear, circular, elliptical); Jones and Stokes formalisms (where included).
   • Birefringence, wave plates, polarizers; Malus’s law and experimental setups.

5. Optical Instruments & Imaging

   • Microscopes, telescopes, aberrations: types (spherical, chromatic, coma, astigmatism), basic correction strategies.
   • Optical bench experiments often illustrated with worked problems.

6. Modern and Applied Topics

   • Basics of lasers: stimulated emission, population inversion, modes (often introductory).
   • Fiber optics fundamentals (in later editions or addenda).
   • Fourier optics and imaging theory (coverage varies by edition).

Part B: Physical Optics (Wave Optics)

• Interference: Young’s double-slit experiment, Fresnel’s biprism, Newton’s rings (to determine wavelength), and interference in thin films.
• Diffraction: Distinction between Fresnel and Fraunhofer diffraction. Analysis of single-slit, double-slit, and diffraction gratings (resolving power).
