Coherence (physics) - Wikipedia

Temporal coherence is the measure of the average correlation between the value of a wave and itself delayed by τ, at any pair of times. Temporal coherence tells us how monochromatic a source is. In other words, it characterizes how well a wave can interfere with itself at a different time. The delay over which the phase or amplitude wanders by a significant amount (and hence the correlatio… WebApr 23, 2016 · The incoherent signal beside the diffraction peak also continues to grow as the amount of hydrogen increases.
