Abstract

A stroboscope is an instrument which produces brief repetitive flashes of light. There are two types of stroboscopes: mechanical and electronic. The difference between them is not only in their appearance. In a mechanical stroboscope an object is illuminated by an external light source which doesn’t flicker visibly, while in an electronic stroboscope the object is being illuminated by light flashes. The stroboscopic effect is a perceptual illusion that causes objects in periodic motion to appear stationary, moving more slowly in their proper direction or even moving in reverse direction when observed in periodically separated moments. The stroboscopic effect may be also achieved with a camera. Levitating water is one of the perceptual illusions due to the stroboscopic effect. Under stroboscopic light, periodically falling water may appear stationary, falling more slowly or even moving upwards. A part of this thesis was to build a device which demonstrates levitating water. The final look of device is shown in figures 3.28, 3.29 and 3.30.
