Normally, frequencies are computed from 0 to the Nyquist frequency, fs/2 (upper-half of unit-circle). If whole is True, compute frequencies from 0 to fs. Ignored if worN is array_like. plot callable. A callable that takes two arguments. If given, the return parameters w and h are passed to plot. Useful for plotting the frequency response inside ...Formula for the frequency from the wavelength. To calculate the frequency, if you know the wavelength \lambda λ, you need to use the velocity of the wave in the medium it is traveling in, v v. The equation for the frequency is: f = \frac {v} {\lambda} f = λv. Where you can see the three quantities we already introduced. 1. Radio Transmitter: A radio transmitter generates a radio wave signal with a known period.
