“phase speed”的概念、定义、习题解题方法及翻译-物理辞典

单词	phase speed
释义	phase speed(phase velocity) Symbol V_p. The speed of propagation of a pure sine wave. V_p = λf , where λ is the wavelength and f is the frequency. The value of the phase speed depends on the nature of the medium through which it is travelling and may also depend on the mode of propagation. For electromagnetic waves travelling through space the phase speed c is given by c² = 1/ε₀µ₀ , where ε₀ and µ₀ are the electric constant and the magnetic constant respectively
