A wave transfers a disturbance from one part of a material to another. In the ideal case, we can say:
The progressive sine wave, among all the wave forms, is a very useful case for study.
A chronometer is available for evaluation of the wave’s velocity. The navigation buttons enable you to go forward or in reverse, step by step. You can also determine the period (frequency) and the wavelength of the wave in the case of a sinusoidal excitation.
