13 Φεβ 2022 · The equation of a basic sine function is \(f(x)=\sin x\). In this case \(b\), the frequency, is equal to 1 which means one cycle occurs in \(2 \pi .\) If \(b=\frac{1}{2},\) the period is \(\frac{2 \pi}{\frac{1}{2}}\) which means the period is \(4 \pi\) and the graph is stretched.

We can have all of them in one equation: y = A sin(B(x + C)) + D. amplitude is A; period is 2 π /B; phase shift is C (positive is to the left) vertical shift is D; And here is how it looks on a graph: Note that we are using radians here, not degrees, and there are 2 π radians in a full rotation.
The time for one complete up-and-down motion is the simple water wave’s period T. In the figure, the wave itself moves to the right with a wave velocity v w . Its amplitude X is the distance between the resting position and the maximum displacement—either the crest or the trough—of the wave.
22 Μαΐ 2022 · Further, it is possible for a sine wave to be shifted in time compared to some other sine wave or reference. While it is possible to indicate this shift as an absolute time, it is more common to do so as a phase shift, that is, the time expressed as a portion of the period in degrees.
The time it takes to complete on cycle is called the Period and is denoted with the symbol T (T for Time). In the example above, the Period is 10 milliseconds, or T=10 ms. The reciprocal of the Period is the Frequency, f. Thus, f = 1/T. The frequency indicates how many cycles exist in one second.
11 Μαρ 2021 · The difference in the phase of a wave at fixed time over a distance of one wavelength is 2π 2 π, as is the difference in phase at fixed position over a time interval of one wave period. Since angles are dimensionless, we normally don’t include this in the units for frequency.
Use the time numbers in the lower panel to find the period, \(T\), of the wave (the time from when one peak passes a point until the next peak passes the same point). To get an accurate number you can use the step buttons. From the period you measure, calculate the angular frequency, \(\omega\).
