Such waves are called harmonic or sinusoidal waves. They are generated by oscillators moving in simple harmonic motion, like the spring-mass system you studied in 7A.

A sinusoidal wave signal is a type of periodic signal that oscillates (moves up and down), periodically. The geometrical waveform of a sinusoidal signal forms an S-shape wave in one complete cycle. A sinusoidal can be a sine functioned signal or cosine functioned signal. Thus, a sinusoidal signal can be defined as,

A sine wave or sinusoidal wave is the most natural representation of how many things in nature change state. A sine wave shows how the amplitude of a variable changes with time. The variable could be audible sound for example. A single pure note is a sine wave, although it would sound a very plain and flat note indeed with none of the harmonics we …
Consider a sinusoidal wave on a string that is produced by a string vibrator, as shown in Figure 16.16. The string vibrator is a device that vibrates a rod up and down. A string of uniform linear mass density is attached to the rod, and the rod oscillates the string, producing a sinusoidal wave. The rod does work on the string, producing energy ...

Well, sinusoids per se are not that common in nature at all. Even a tiny bit of nonlinearity essentialy corrupts the pure sine behavior of the idealized oscillator (see the van der Pol and the Duffing oscillators for some popular weakly nonlinear extensions).

A wave with a shorter period will oscillate more rapidly, while a wave with a longer period will oscillate more slowly. This is because the shorter the period, the faster the wave will move. The period of a sinusoidal wave is an essential property that determines the wave's general structure as well as its conduct. Phase Shift of a Sinusoid
