13.2 Wave Properties: Speed, Amplitude, Frequency, and Period
Period—time it takes for one wave cycle to complete. In addition to amplitude, frequency, and period, their wavelength and wave velocity also characterize waves. The wavelength λ is the distance between adjacent identical parts of a wave, parallel to the direction of propagation. The wave velocity v w is the speed at which the disturbance moves.

INTRODUCTION TO VIBRATION- BASED CONDITION
AMPLITUDE. Amplitude represents the intensity of motion from a neutral position over a time interval or at a specific time. Amplitude can be expressed/measured as displacement, velocity and acceleration of motion. It is measured in mm, mm/s, mm/s2, g (9.81 m/s2), dB, etc. As seen in Figure 1, amplitude is represented by arrows.
