Frequency. The frequency of a sine wave is the number of complete cycles that happen every second . (A cycle is the same as the period, see below.) In the bouncing weight above, the frequency is about one cycle per second. In general, a sine wave is given by the formula.

A general form of a sinusoidal wave is y(x,t)=Asin(kx−ωt+ϕ) y ( x , t ) = A sin ( kx − ω t + ϕ ) , where A is the amplitude of the wave, ω is the wave’s angular frequency, k is the wavenumber, and ϕ is the phase of the sine wave given in radians.
