Le programme
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
- Light guidance
- Light rays propagation in a homogeneous, inhomogeneous medium
