i want to know how i get the wavelength/frequency of a seismic wave, if i only have a gaussian source and the velocity (c = 4000m/s) of a medium given.
e.g. for a ricker wavelet it would be easy to get the central frequency and max frequency of the source to compute the wavelength by c/f, but i have some issues with the gaussian and unfortunately only signals of a gaussian source.
Let's assume my source time function in time domain looks like this:
source = 1/(2* np.pi * 17.**2) * np.exp( - (t-100)**2 / (2* 17.**2))
So a gaussian with variance of 17 squared and shifted to the right. In the frequency domain it will be centered around zero and i dont really get a maximum frequency as well. Is there a way to find these?
