Persistence of Vision

  1. Dec 10, 2007 #1
    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.

    the intensity will be spread around the circle.
