What are the necessary conditions of interference of light waves?

In: Physics [Edit categories]

Answer:

The two sources of light should emit continuous waves of same wavelength and same time period i.e. the source should have phase coherence.
The two sources of light should be very close to each other.
The waves emitted by two sources should either have zero phase difference or no phase difference.
