Two sources are said to be coherent if they emit the waves of same wave length and same
amplitude and constant phase difference. The two slits illuminated by a single source, acts as
coherent sources.

PHASE DIFFERENCE BETWEEN THE TWO SOURCES ARE EITHER ZERO ARE CONSTANT, THEN THE TWO SOURCES ARE CALLED COHORENT SOURCES.

when two sources of light has 0 or constant phase difference between them,then it called cohorent sources.

The two sources of light, whose frequencies (or wavelength λ ) are
same and the phase difference between the waves emitted by which remains constant with
respect to time are defined as coherent sources.
They are obtained from the same single source.
Laser light is highly coherent and monochromatic.
The distance between them is small.
These can be apparent or real.
Their state of polarization is the same.
