The wagon-wheel effect (alternatively called stagecoach-wheel effect) is an optical illusion in which a spoked wheel appears to rotate differently from its true rotation. The wheel can appear to rotate more slowly than the true rotation, it can appear stationary, or it can appear to rotate in the opposite direction from the true rotation ...
It accounts for the "wagon-wheel effect", so-called because in video, spoked wheels (such as on horse-drawn wagons) sometimes appear to be turning backwards. A strobe fountain, a stream of water droplets falling at regular intervals lit with a strobe light , is an example of the stroboscopic effect being applied to a cyclic motion that is not ...
The Vertical-horizontal illusion is the tendency for observers to overestimate the length of a vertical line relative to a horizontal line of the same length. Vista paradox: Visual tilt effects: Wagon-wheel effect: White's illusion: Wundt illusion: The two red vertical lines are both straight, but they may look as if they are bowed inwards to ...
English: This illusion only occurs when the rotating disc is recorded with a camera. Depending on how far each spoke travels between the camera snapshots, the movement follows. If the inner wheel has a speed lower than 288 rpm (or 4,8 revolutions/second) it will seem to rotate backwards. The camera captured 24 fps.

Stroboscopic effect, a phenomenon that occurs when continuous motion is represented by a series of short or instantaneous samples Wagon-wheel effect, temporal aliasing effect in which a spoked wheel appears to rotate differently from its true rotation
A physical motion of a camera at a constant shutter speed may create temporal aliasing known as the wagon wheel effect. The velocity of the camera, moving towards the right, constantly increases at the same rate (while to the camera, the objects appear sliding to the left).
