group speed (also group velocity)
-
1.
N the speed at which energy is propagated in a wave. This is the quantity determined when one measures the distance which the radiation travels in a given time. In a medium in which the speed increases with wavelength the group speed is less than the phase speed, and vice versa 群速 [physics]

-
When the medium density increases (with more atoms), the slow group velocity decreases.
当介质的密度增加时（包含更多的原子），群速度就降低。

Although previous studies have found that the "group velocity" of light can travel faster than c, the "signal velocity" -the speed at which information travels -cannot.
尽管先前的研究已经证实，光的“群速度”可以超越光速c，而“信号传播速度”——光携带的信息的传播速度——不能超越光速。
