WebCoherent vs. Incoherent Wave sources Definition: Two sources are considered coherent if they emit waves that maintain a constant phase relation. Effectively, this means that the waves do not shift relative to one another as time passes. WebCoherence describes the properties of the interrelation between physical quantities of a single wave or between several waves. Two waves are coherent when they have a constant relative phase or when they have zero or constant phase difference and the same frequency. Coherence is also the property which enables waves to have stationary interference.

WebIn the case of light, incoherent scattering is called “Rayleigh” scattering when it is elastic. It is a common process that makes us see objects with our eyes, which detect light scattered by these objects. Thus leaves appear green as chlorophyll pigments scatter green light, while it absorbs blue and red lights and is transparent for green light. WebJun 23, 2016 · You can also get superposition states with incoherent light, but those are not very useful. The word coherent is used to describe the superposition states that you create with coherent fields.
