Glossary
- Interference: superposition of light waves whose resulting intensity depends on the phase shifts between them
- Wavelength ( of a light wave ): distance between two consecutive identical states of the electric ( or magnetic ) field
- Optical path ( or optical length ): product of a length (along the path of a light ray) by the refraction index of the medium
- Phase shift: characterizes the temporal shift between two light waves
- Relative intensity: normalized intensity as determined by the ratio between the intensity and its maximum value
