Web26 apr. 2024 · It is called the envelope, and has wavenumber and frequency . It moves with a speed , called the group velocity, This velocity may be radically different from the phase velocity . More generally, we can write the group velocity as. Sum of two waves, showing the carrier and envelope. WebThe speed of propagation vw is the distance the wave travels in a given time, which is one wavelength in a time of one period. In equation form, it is written as v w = λ T 13.3 or v w = f λ. 13.4 From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. See Figure 13.8. inspire asl
