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
