Импеданс, русский
Обозначает сопротивление микрофона или наушников переменному току. зависит от частоты и, если дается для частоты 1 кгц, то называется номинальным. единицей измерения является ом. в последние годы был разработан промышленный стандарт, предусматривающий для наушников импеданс 50 - 600 ом. при работе с микрофоном входной импеданс последующего в тракте усилителя должен быть как минимум в три раза выше номинального импеданса микрофона, чтобы не ослаблять уровень микрофонного сигнала.

Index of refraction, английский
- The ratio between the angle of incidence to the angle of refraction of light. index varies depending on the density of the medium. the denser the medium, the higher the index.
- The speed of light in a vacuum divided by the speed of light in a material, abbreviated n, which measures how materials refract light.
- The degree to which a lens material refracts (bends) light. this results from the ratio of the speed of light in air to the speed of light through a lens substance; the higher the index of lens material, the quicker light rays are bent as they pass through the lens. the higher the index, the more the refractive power of the lens.
- Коэффициент отражения; показатель преломления
- Ratio of the velocity of light in one medium to its velocity in a second medium as the light passes from medium to medium. if a medium is crystalline, the velocity may depend on the direction of the light with respect to the crystalline axes and the substance may have several indexes of refraction, i.e., it may be birefringent. (also see birefringence.)
- Ratio of velocity of light in a vacuum to velocity of light in a material. see also refractometer.
