Number
complete oscillations of the water particles will correspond to the number of complete oscillations of the float.

Typically, the velocity of propagation is usually expressed in centimeters or meters per second. Since the oscillation period is expressed in seconds, the wavelength is expressed, respectively, in centimeters or meters.

This applies not only to the waves on the water or in the air, but also to the airwaves.
Everyone knows that the "magnitude" of the waves may be different. Under the wave amplitude, or any other of the oscillatory process is understood as the largest deviation from the mean position.
Waves in the air have a large range of frequencies. Along with simple acoustic waves can be difficult. Complex sounds are characterized by the simultaneous presence of oscillations with multiple frequencies. These sounds are composed of the fundamental frequency (the lowest) and frequencies that are multiples of the basic (higher). Last known harmonics of the fundamental frequency. The presence of harmonics can distinguish individual voices and describes the timbre or "color" the sound. |
