Question
Answer the following question:
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. Explain why?
✓

Answer

A bright spot is seen at the center of the shadow of objective because, wave diffracted from the edge of the circular obstacle interface constructively at the centre of the shadow producing a bright spot.
