Solution

Diffraction:

  1. Diffraction is the bending of light waves around the corners of obstruction and the spreading of light waves into the simple geometric shade.
  2. The core part of the fringe system is bright in Young's double-slit experiment for light interference. If light travels in a straight line, the center region, that is the screen's shadow between the two slits, should seem black.

Here,

D is the distance between slit and screen.

a is the width of the slit.
