SUMMARY
Coherent light waves must have the same frequency to maintain a constant phase difference, which is essential for coherence. Coherence is defined by two main types: temporal coherence, which is influenced by frequency spread, and spatial coherence, which relates to the size of the light source. Lasers typically produce temporally coherent but spatially incoherent light, while distant stars exhibit the opposite characteristics. Understanding these distinctions is crucial for applications in optics and photonics.
