WebThe input single slit isolates radiation from a small region of an incoherent source, which ensures that the radiation arrives at the double slits phase related. The coherence length is short, but that doesn't change the phase difference at the slits. Small frequency range reduces color fringing. – Nov 10, 2013 at 8:15 WebThese waves can interfere constructively to give bright fringes. Examples include laser lights. Incoherent sources of light. These are exactly opposite to coherent sources. We call two sources incoherent sources if they produce 2 waves that are not in phase and have different frequencies and waveforms.

WebStudents must first understand two terms: coherent and incoherent light.
