Topics

  1. Diffraction:
    • (a) Fraunhofer Diffraction: Single slit; Double Slit. Multiple slits and Diffraction grating.
    • (b) Fresnel Diffraction: Half-period zones. Zone plate.
  2. Polarisation: Transverse nature of light waves. Plane polarized light, production and analysis. Circular and elliptical polarization. Optical activity.

Remarks

  • Typical transmission grating costs 150-200$ + shipping, roughly 15K INR. Typical replica grating in India costs Rs.500/-.
