An instrument to determine optimal distance and time interval for occurrence of Phi Phenomenon Apparatus.
It consists of a wooden box having arrangement of a pair of lights in shape of dots and arrows.
The distance between a pair of light can be adjusted and recorded with the help of two knobs that slide over a scale.
The flickering of the light can be varied with the help of an arrangement provided on front panel.
There is a window at the rear to observe the lights.
When a subject is made to observe two lights at a particular frequency, the distance is so varied that at a particular
distance the two lights appear a continuous light.
The experiment is repeated at different frequencies and with different shape of light.
