Coherent

Coherent describes a consistent and logical connection between ideas, parts, or elements, where everything fits together smoothly. In science and engineering, it often refers to waves—like light or sound—that are in sync, with their peaks and troughs aligned, allowing them to produce clear and stable patterns. Coherence ensures that information or signals are organized, reliable, and maintain a stable relationship over time or space, making communication, imaging, or measurements accurate and meaningful.
