When the interference occurs with coherent sources, _______ of the superimposing
waves add like _______.

Q. Assertion :In Young's double slit experiment interference pattern disappear when one of the slits is closed. Reason: Interference occurs due to superimposition of light waves from two coherent sources.

Q. Assertion :Two coherent point sources of light having non-zero phase difference are separated by a small distance. Then, on the perpendicular bisector of line segment joining both the point sources, constructive interference cannot be obtained. Reason: For two waves from coherent point sources to interfere constructively at a point, the magnitude of their phase difference at that point must be

2 m π
