WebThe combination of the first three features suggests a fourth – K-wave processes are anything but uniform over time and space. Their effects are neither instantaneous nor are they experienced equally across space. Finally, the unevenness of the K-wave's geographical diffusion is matched by the unevenness of the innovation source's advantage. WebIn mathematics, physics, and engineering, spatial frequency is a characteristic of any structure that is periodic across position in space.The spatial frequency is a measure of how often sinusoidal components (as determined by the Fourier transform) of the structure repeat per unit of distance.The SI unit of spatial frequency is cycles per meter (m).
