Coherent light sources are sources of light that emit waves that are consistent in phase and frequency over time, allowing for stable interference patterns. This coherence is crucial for phenomena such as interference and diffraction, as it ensures that the light waves can superimpose constructively or destructively, leading to observable patterns and intensity distributions. Coherence plays a key role in various optical applications, including lasers and interferometry, making it a fundamental concept in wave optics.
congrats on reading the definition of coherent light sources. now let's actually learn it.
