The spatial frequency refers to how many complete periods the signal goes through for a given unit of distance (eg. cylcles/m) while the temporal frequency refers to how many complete periods the signal goes through for a given unit of time (eg. cyles/s or Hz).

What is the spatial frequency of a wave?
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).
What is spatial frequency in simple terms?
"Spatial frequency" refers to the number of pairs of bars imaged within a given distance on the retina. One-third of a millimeter is a convenient unit of retinal distance because an image this size is said to subtend one degree of visual angle on the retina.
What is an example of spatial frequency?
Spatial frequency describes the periodic distributions of light and dark in an image. High spatial frequencies correspond to features such as sharp edges and fine details, whereas low spatial frequencies correspond to features such as global shape.
What is spatial wavelength?
The measure of spatial periodicity is called wavelength. Wavelength is the distance between the closest two points in the wave that are exactly in the same state. The distance between two adjacent crests is the same as the distance between two neighbouring troughs, and this distance is equal to the wavelength.
