How do you receive coherent sources?
Usually coherence in interference is obtained by two strategies (1) Division of wave entrance the place wavefront is split into two elements by reflection, refraction or diffraction and people two elements reunite at a small angle to provide interference as executed in case of Younger’s double slit experiment and Fresnel’s biprism …
