(a) State the importance of coherent sources in the phenomenon of interference.
(b) In Young’s double slit experiment to produce interference pattern, obtain the
conditions for constructive and destructive interference. Hence, deduce the expression
for the fringe width.
(c) How does the fringe width get affected, if the entire experimental apparatus of Young
is immersed in water?

Answer:
In Young's double slit experiment to produce interference pattern, obtain the conditions for constructive and destructive interference. ... If coherent sources are not taken, the phase difference between two interfering waves, will change continuously and a sustained interference pattern will not be obtained.
