Speed of propagation of a wave in a medium
WebConsider the propagation of an electromagnetic wave through a uniform dielectric medium of dielectric constant . According to Eqs. According to Eqs. ( 810 ) and ( 812 ), the dipole moment per unit volume induced in the medium by the wave electric field is The velocity factor (VF), also called wave propagation speed or velocity of propagation (VoP or ), of a transmission medium is the ratio of the speed at which a wavefront (of an electromagnetic signal, a radio signal, a light pulse in an optical fibre or a change of the electrical voltage on a copper wire) passes through the medium, to the speed of light in vacuum. For optical signals, the velocity factor is the reciprocal of the refractive index.

WebIf the crest of an ocean wave moves a distance of 20 meters in 10 seconds, then the speed of the ocean wave is 2.0 m/s. On the other hand, if the crest of an ocean wave moves a distance of 25 meters in 10 seconds (the same amount of time), then the speed of this ocean wave is 2.5 m/s. eagle picking up small dogWebThe 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 13.3 v w = λ T or 13.4 v w = f λ. 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. cslb tests datesWebLongitudinal Wave. Particles move in the same direction. Transverse Wave. Particles on the medium oscillates. Perpendicular.
