{wiki=Coherence_(physics)}
In physics, particularly in the context of wave phenomena, coherence refers to the correlation between different parts of a wave or between different waves. Coherence is a crucial concept in various fields such as optics, quantum mechanics, and signal processing. There are two main types of coherence: 1. **Temporal Coherence**: This refers to the correlation of the phase of a wave at different points in time.
