Topics in Wave Optics

1

Nature of Light and Huygens' Principle

  • Light exhibits dual nature - both particle (corpuscular) and wave characteristics
  • Corpuscular theory by Newton explained reflection and refraction but failed for interference and diffraction
  • Wave theory by Huygens successfully explained all optical phenomena including new discoveries
2

Reflection and Refraction Using Wave Theory

  • Huygens' principle explains laws of reflection and refraction
  • During reflection: angle of incidence = angle of reflection (i = r)
  • During refraction: n₁sin i = n₂sin r (Snell's law)
3

Polarization of Light

  • Unpolarized light has electric field vibrating in all directions perpendicular to propagation
  • Polarized light has electric field restricted to one direction
  • Polaroids are materials that allow only specific orientation of electric field to pass
4

Young's Double Slit Experiment and Interference

  • First experimental proof of wave nature of light
  • Two coherent sources obtained from single source using double slit
  • Interference produces alternating bright and dark fringes
