WebCoherence In wave optics, we make a distinction between coherent and incoherent sources of light. Any real source of light is not exactly monochromatic (single color), but has a range or band of frequencies, Δ f. An incoherent source of light lacks a specific direction and has a relatively large Δ f. By contrast, a coherent source has a specific direction with a much …
