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 rotational. When viewed under normal light, this is a normal water fountain.
Stroboscopic effects are caused by aliasing that occurs when continuous rotational or other cyclic motion is represented by a series of short or instantaneous samples (as opposed to a continuous view) at a sampling rate close to the period of the motion. Rotating objects can appear counter-rotating, stationary, or rotating under a strobe light.
Strobo Trip - Light & Audio Phase Illusions Toy is a toy box containing a stroboscope light and a memory stick with three tracks of music composed by the band The Flaming Lips. After the announcement in early May, [ 1 ] it was released on September 20, 2011 at 5 pm, and is known for the 6-hour long track "I Found a Star on the Ground."
When it was introduced in the French newspaper Le Figaro in June 1833, the term 'phénakisticope' was explained to be from the root Greek word φενακιστικός phenakistikos (or rather from φενακίζειν phenakizein), meaning "deceiving" or "cheating", [2] and ὄψ óps, meaning "eye" or "face", [3] so it was probably intended loosely as 'optical deception' or 'optical illusion'.
A strobe light flashing at the proper period can appear to freeze or reverse cyclical motion. A stroboscope, also known as a strobe, is an instrument used to make a cyclically moving object appear to be slow-moving, or stationary.
Strobe or STROBE may also refer to: Strobe effect , the apparently slowed down or reversal of periodic processes that are only observed at certain, regularly successive time intervals, for example by means of light flashes ( stroboscopes ) or a rotating disk with windows that only temporarily reveal the view.
In a dark room, this clearly shows the waveform. Otherwise, one can use bending or, perhaps more easily, by adjusting the machine heads, to obtain the same, or a multiple, of the AC frequency to achieve the same effect. For example, in the case of a guitar, the 6th (lowest pitched) string pressed to the third fret gives a G at 97.999 Hz.
The stroboscopic effect makes each seem to be a single animated object. By allowing the rotation speed to be slightly out of synchronization with the strobe, the animated objects can be made to appear to also move slowly forwards or backwards, according to how much faster or slower each rotation is than the corresponding series of strobe flashes.
