The program
Nature of light, reflection phenomena and refraction
  • Waves and particles (light rays)
  • Diversity of light sources, UV spectrum, visible, IR, white light, laser
  • Free and guided propagation (fiber optics)
  • Plan mirror: paths of incident and reflected rays
  • Refractive index of a transparent medium
  • Path of light in a parallel-sided blade and in a prism (dispersion)
From the simple lens to the operation of an optical instrument
  • Tracing of elementary rays in a lens
  • Convergent, divergent lenses
  • Position of an object and its image, magnification
  • Eye, photo lens, magnifying glass, telescope, microscope
Wave phenomena
  • Interferences: principle, summation of two vibratory waves
  • Illustrations: thin blades (soap bubbles, oil films), optical treatments, filters
  • Diffraction: origin of the phenomenon (wavelet sources)
  • Illustrations: diffraction by a slot, grating, compact disc, hologram
Experimental demonstrations and practical work
