Stroboscopic Flash
Flashing lights can trick your brain into seeing wheels spin backward in time
13 days ago

Why does a rotating wheel appear to spin backward under a stroboscopic flash?
Because the wheel physically reverses its rotation when exposed to flashing light.
Because the stroboscopic flash changes the wheel's color, affecting perception.
Because the flash samples the wheel's position at intervals close to its rotation period, causing aliasing.
