We know that lightwave emitted from an ordinary light source undergoes abrupt phase changes in time intervals of the order of 10-10 s. Thus, the light waves coming out from two independent light sources will not have any fixed phase relationship and would be incoherent.
Class 12 Physics Chapter 10 Wave Optics Session 2024-2025.
State the reason, why two independent sources of light cannot be considered as coherent sources.
