APAKAH MAKSUD PHASE SPEED dalam CORSICA?
Halaju fasa
Halaju fasa gelombang adalah kadar di mana fasa gelombang menyebarkan di ruang angkasa. Ini adalah halaju di mana fasa mana-mana satu komponen frekuensi gelombang bergerak. Bagi komponen sedemikian, mana-mana fasa gelombang tertentu akan muncul untuk bergerak pada halaju fasa. Halaju fasa diberikan dari segi panjang gelombang λ dan tempoh T sebagai Or, bersamaan dengan frekuensi sudut gelombang ω, yang menentukan perubahan sudut per unit masa, dan gelombang k, yang mewakili kekompadanan antara frekuensi sudut ω dan kelajuan linear νp: Untuk memahami di mana persamaan ini berasal, bayangkan gelombang sinus asas, A cos. Diberi masa t, sumber menghasilkan ωt / 2π = ft oscillations. Pada masa yang sama, hadapan gelombang awal menyebarkan jauh dari sumber melalui ruang ke jarak x untuk memenuhi jumlah ayunan yang sama, kx = ωt. Sehingga halaju penyebaran v adalah v = x / t = ω / k.
Definisi phase speed dalam kamus Corsica
Takrif kelajuan fasa dalam kamus adalah kelajuan di mana fasa gelombang disebarkan, hasil masa kekerapan panjang gelombang. Inilah kuantiti yang ditentukan oleh kaedah menggunakan gangguan. Dalam medium penyebaran ia berbeza dari kelajuan kumpulan Juga dipanggil: kelajuan gelombang, halaju gelombang.

Foundations of Biomedical Ultrasound
As its name implies, the phase speed of a wave is the speed with which any
given phase of the waveform propagates to a new spatial location. For a simple
harmonic wave the phase speed can be determined from the time taken for a
given ...

(1.18) Likewise, the phase speed in the z-direction is (1.19) Note also that if we
multiply (1.14) by a/ and use (1.16) we get + - - (1.20) Vzr indicating that phase
speed is not a vector. In textbooks and the scientific literature, we will see ...

The frequency remains constant as they move into shallow water, so by (5.3.8)
the waves become shorter and the phase speed decreases. For instance, when
the depth is reduced to 1 m, the wavelength of a 10-s wave is 30 m and the
phase ...

The term phase speed refers to the propagation speed, v, of a sinusoidal wave.
Overlapping sinusoidal waves of different frequencies interfere, resulting in a
propagating INTERFERENCE pattern, such as a pulse. The speed of
propagation of ...
