In a single slit diffraction experiment, 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?
State two points of difference between the interference patterns obtained in young's double slit experiment
and the diffraction pattern due to a single slit.

Answer:
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. This is because light waves are diffracted from the edge of the circular obstacle, which interferes constructively at the centre of the shadow.
