  Light displays particle and wave properties within the bounds of the
inequality, K^2+V^2<=1, where K represents particle information and V
represents corresponding wave information. Using two laser beams that cross and
then diverge from each other we explore the inequality. Results, based on
semiclassical analysis, are in conflict with the inequality. However, analysis
based on quantum electrodynamics resolves the conflict and uncovers a region
where particle and wave aspects of light develop independently. Independent
development of wave and particle aspects implies that they represent separate
realities.
