SUMMARY
Coherent sources are defined as sources that maintain the same frequency and a constant phase difference. While some literature suggests that a constant phase difference alone qualifies as coherence, this is misleading. If two waves have different frequencies, they cannot maintain a constant phase difference over time. Therefore, both the same frequency and a constant phase difference are essential for coherence.
