WebbThe above discussion holds true for any component, regardless of its angular frequency of ω.. The limiting case of c 2 = 0 corresponds to a "fixed end" that doesn't move, whereas …

WebbThe difference in those phase shifts is called retardance. It can be specified in radians (rad) or in degrees (°), alternatively in terms of wavelengths; a retardance of λ, for example, corresponds to 2 π or 360°. In optics, a retardance is often introduced by inserting a waveplate – for example, a π retardance with a λ /2 plate. Webb(f) The reflectance for internal reflection varies continuously for h i < h c , and becomes 100% for total internal reflection. (g) The phase shift for internal reflection is either 0 or …
