Why no interference pattern is observed when two coherent sources are a) too close b) very far apart?
Asked by Topperlearning User | 12 Jun, 2014, 07:11: AM
answered-by-expert Expert Answer

a) When two coherent sources are too close , distance (d) between them tends to zero and hence no interference pattern will be observed

b) When the distance between them becomes too large , fringe width becomes too small and may no longer be in the visible region. Hence no interference pattern will be observed.
