Study route
29.1. Geometric optical performance
The beam model is applicable when the size of the barrier is much longer than the wave length, and it describes images of the laws of reflection and refractory.
29.2 Interference and diffusion
- Coherent waves create a steady redistribution of intensity, and it becomes visible when the size of the hole or barrier is comparable to the length of the wave.
29.3. Polarization of light
- Polarization describes the orientation of the fluctuations in the electric field; it proves the transverse nature of the light and is used to control the lights and contrasts.
