What is the difference between the magnitude and the phase spectrum of the Fourier transform?

1 April 2022 Enpatika.com Genel

The magnitude is the square root of the sum of the squares of the real and imaginary parts and the phase is the arctan(Im/Re) , so you can plot these individually and see how the amplitude varies over frequency and also any phase shifts that may occur at different frequencies.2 Haz 2020

What is the magnitude of a wave?

Its magnitude is either the wavenumber or angular wavenumber of the wave (inversely proportional to the wavelength), and its direction is ordinarily the direction of wave propagation (but not always; see below).
