Introduction
Coherence and Interference are two ideal wave features that complement each other,.The wave interference interference  do occur but for it it  to be considered constructive,it it  needs the coherence of some 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 cohering requires that they ( waves) must be in phase -requires that  the wave  are in  phase,their peaks are line up with alinged with each other.
