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.10 Ara 2015
Read moreWhat is spatial frequency in vision?
“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.

The hertz measurement, abbreviated Hz, is the number of waves that pass by per second. For example, an “A” note on a violin string vibrates at about 440 Hz (440 vibrations per second).
Read moreHow do you find the frequency of a wave?
To calculate the frequency of a wave, divide the velocity of the wave by the wavelength . Write your answer in Hertz, or Hz, which is the unit for frequency. If you need to calculate the frequency from the time it takes to complete a wave cycle, or T, the frequency will be the inverse of the time, or 1 divided by T.
