Coherence and Interference
Ø Introduction
...
Coherence and Interference are two ideal wave features that complement each other.The wave interference do occur but for it to be considered constructive interference,it needs the coherence of some of the physical quantities of the waves involved; the wavelength, amplitude, and phase of the constituent wave forms must be identical.The most distinct concept of coherence in waves requires that the wave are in phase,their peaks are aligned with each other.
Interference
Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium.
