Why are coherent sources necessary to produce a sustained interference pattern?
Why are coherent sources necessary for observing a sustained interference pattern?

उत्तर
As interference results from the superposition of waves, coherent sources are required to observe a continuous interference pattern. The phase difference between the waves will fluctuate randomly over time if the sources are not coherent, creating an interference pattern that fluctuates quickly and cannot be maintained.
