WebbHowever, the slow phase velocity envelope during per- or post-rotatory nystagmus is more accurately represented by two exponential modes. One represents activity in the vestibular nerve induced by deflection of the cupula, the other by activation that the input from the canals produces in the central velocity storage integrator. WebbLikewise, during the sustained magnetic vestibular stimulation (MVS), slow-phase velocity slowly decays back toward a new, but non-zero, baseline (16, 17). When the adaptive stimulus is abruptly removed, an after-effect appears, revealing the prior adaptation with oppositely directed slow phases that slowly fade away. When light propagates through a material, it travels slower than the vacuum speed, c. This is a change in the phase velocity of the light and is manifested in physical effects such as refraction. This reduction in speed is quantified by the ratio between c and the phase velocity. This ratio is called the refractive index of the material. Slow light is a dramatic reduction in the group velocity of light, not the phase velocity. Slow light effects are not due to abnormally large refractive indices, … headphone effects

In TEM waves, the phase velocity is the same as the velocity of light in the chosen medium. For waveguide, the phase velocity is more complicated: After some rearranging we can arrive at: goldshell ip reporter
