Assertion (A) : When tiny circular obstacle is placed in the path of light from some distance, a bright spot is seen at the centra of the shadow of the obstacle. Reason (R ) : Destructive interference occurs at the centre of the shadow.

A: When a tiny circular obstacle is placed in the path of light from a distant source, a bright spot is seen at the centre of the shadow of the obstacle. R: Waves diffracted from the edge of the circular obstacle interfere constructively at the centre of the shadow producing a bright spot.
