Persistence of Vision!!!!!!!!!!!! If you wave a 5mm bright green led in a circle fast enough you see a green circle (say you attach it to a bike wheel and spin the wheel). What will the intensity of that green circle be? Will the light intensity be smeared throughout the whole circumference of the circle? Or will the light intensity of the green circle be similar in light intensity to the light intensity of that 1 green led? I am trying to make a persistence of vision display that would be sunlight visible, so this is why I need to find an answer somehow. Any help would be appreciated.
