Every rainbow I've ever seen after a storm and when the sun shines through, seems to be at the same distance each time. I would estimate about 400-500 meters. Also, it remains the same distance away from you as you move closer, hence the reason you never find the pot of gold at the end of the rainbow.
So I was wondering if there was a constant for this distance that light has to be from the sun reflecting back through the prism of a raindrop, to the viewer in order to create the rainbow.
