t}} = \frac{{\Delta v}}{{\Delta t}} = \text{acceleration}\) The area under a velocity-time graph gives the displacement. The velocity-time and acceleration-time graphs for common motions are shown ...

A frequency of 50 Hz means there are 50 vibrations every second. A displacement-time graph is a way to measure the time period of a wave. This wave has a time period of 0.1 seconds. Wavelength is ...
