Assertion: Light form two cohetent sources is reaching the screen. If the path difference at a point on the screen for yellwo light is

3 \lambda / 2

, then the fringe at the point will be coloured.

Reason: Two cohernent sources always have constant phase relationship.

View answer and explanation

Correct option: D

Assertion is false and Reason is true

Option D (Assertion is false and Reason is true) is correct because a path difference of 3λ/2 results in destructive interference, not a colored fringe.
