Wave

The following terms are often used in the study of waves:

Wave number: k
Frequency: f
Wavelength: λ
Period: T
Phase velocity: vp
Angular frequency: ω

The following equations shows the relationship between these terms.

Wave number
k = 2/λ

Frequency
f = 1/T = ω0 / 2

Angular Frequency
ω0 = 2 · · f = 2 / T

Phase Velocity
vp = ω / k = λ · f

Period
T = 2 / ω0 = 2 · √(m/k)

Harmonic Wave
x = A · cos(ω0 · t + ø)

Where ø is the phase constant and A is the amplitude.
