*Coherent sources produce waves that are in sync, having a constant phase relationship.
*Necessary for producing clear interference patterns.
*Coherent waves are typically monochromatic and have the same frequency.
*Essential in applications like lasers, holography, and interferometry. Coherence can be temporal (constant phase difference over time) or spatial (constant phase difference
*Coherence can be temporal (constant phase difference over time) or spatial (constant phase difference
across space).
*The degree of coherence affects the visibility and contrast of interference fringes.
*Achieving coherence often involves stabilizing the frequency and phase of the wave sources.
