WebThe magnitude of the wave velocity is the distance the wave travels in a given time, which is one wavelength in the time of one period, and the wave speed is the magnitude of wave velocity. In equation form, this is. v = λ T = λ f. 16.1. This fundamental relationship holds for all types of waves. WebGround waves occur as the signal spreads out from the trans-mitter in all directions. Instead of traveling in a straight line (and not being heard beyond the visual horizon), radio signal tends to follow the curvature of the Earth. This occurs because currents are induced in the surface of the Earth, which slows the wavefront near the ground.
