A model seismic wavelet.

The amplitude *A* of the Ricker wavelet with peak frequency *f* at time *t* is computed like so:

Sometimes the period (somewhat erroneously referred to occasionally as the wavelength) is given as 1/*f*, but since it has mixed frequencies, this is not quite correct, and for some wavelets is not even a good approximation. In fact, the Ricker wavelet has its sidelobe minima at

These minima have the value
