Can we accurately describe light as exclusively a wave or just a particle? Are the two mutually exclusive? In this third part of his series on light and color Colm Kelleher discusses wave-particle duality and its relationship to how we see light and therefore color. \[Directed by Nelson Diaz, narrated by Colm Kelleher\].
