A stroboscopic light, or strobe light, is a device which discharges flashes of light which causes moving objects to appear stationary or slow-moving. The flashing light has been known to cause seizures in people who suffer from epilepsy.
The stroboscopic effect is caused by the flickering of light at a frequency that can appear as slow motion or frozen movement. Incandescent lamps do not typically exhibit this effect because they emit a continuous spectrum of light without noticeable flickering like some other light sources.
Stroboscopic movement is an optical illusion where still images presented in quick succession create the perception of continuous motion. It is commonly used in animations, movies, and video games to create the illusion of movement.
A traffic light is a light source as it emits light to signal drivers when to stop, slow down, or go.
A red light will be needed to combine with magenta light to produce green light. Green light is the complementary color to magenta, so by mixing red light with magenta light, the result will be green light.
Mixing red light and blue light produces magenta light.
The stroboscopic effect is caused by the flickering of light at a frequency that can appear as slow motion or frozen movement. Incandescent lamps do not typically exhibit this effect because they emit a continuous spectrum of light without noticeable flickering like some other light sources.
To eliminate the stroboscopic effect, you can adjust the lighting conditions by using continuous light sources instead of flickering ones, such as LED lights with a high refresh rate. Additionally, synchronizing the camera's shutter speed with the frequency of the light source can help reduce the effect. Using slower frame rates in video capture can also minimize the stroboscopic perception. Finally, employing motion blur techniques in post-production can help smooth out any visual artifacts.

A stroboscope uses a series of flashes to make a fast moving object seem slower. A stroboscopic tachometer has a scale that reads either in revolutions per minute or flashes per minute.

Whilst some propellers are comparatively slow there is an effect called the stroboscopic effect, which at certain revolutions, synchronise reflected light from the blades. This fools the eye into believing the propellers are turning much more slowly than they are.

Stroboscopic effects can be dangerous primarily due to their potential to trigger seizures in individuals with photosensitive epilepsy, as rapid flashing lights may induce seizures. Additionally, strobe lights can cause disorientation and impaired vision, leading to accidents in environments like dance clubs or during emergency situations. Prolonged exposure can also lead to eye strain or headaches for some individuals. Therefore, caution is essential when using strobe lighting in public spaces.

The stroboscopic effect refers to the visual phenomenon where a series of still images or frames presented in rapid succession create the illusion of motion. This effect is often observed in film and animation, where the persistence of vision allows the brain to perceive movement despite viewing separate static images. It can also occur in real life, such as when a rotating object appears to move slowly or in reverse under flickering lights. This effect highlights the limitations of human perception in interpreting rapidly changing visual stimuli.
