how to find frequency of a wave math. For these purposes we can ignore the phase shift part and we can also understand A to simply mean the size of the wave with 1 being its maximum in terms of the unit circle. Number of complete waves passing a point in a given time f number of cycles t If 10 waves pass in 1 second the frequency is 10 Hz If 6 waves pass in 2 seconds the frequency is 3 Hz.

The frequency represented by the Greek letter nu n is the number of waves that pass a certain point in a specified amount of time. You can also enter in the wavelength and this calculator will calculate the corresponding frequency. In general a sine wave is given by the formula.
Multiply pi by two.
The mathematical equation representing the simplest wave looks like this. You can also enter in the wavelength and this calculator will calculate the corresponding frequency. We see that a sine wave is a function that shows the position of the angular frequency of the wave at time t expressed in radians and offset by a phase shift if present. Typically frequency is measured in units of cycles per second or waves per second.
