Question
For the sustained interference of light, the necessary condition is that the two sources should : -
Options
A.have constant phase difference
B.be narrow
C.be close to each other
D.of same amplitude
Solution
Sustained interference means a interference pattern (arrangement of fringes) can not be change with time. It is only possible when the phase difference between at a point does not change with time.
