Sinusoidal Waves. When a string is shaken sinusoidally, i.e., it is vibrated such that the oscillations are sine or cosine function of time, the wave propagated in the string also has sinusoidal shape as illustrated in Figure 14.1.1. The period of the wave in space is called its wavelength, and it is usually denoted by the Greek letter λ ...

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 = 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.
