Expert Solution
Concept and Principle:
  • Light is capable of interfering with each other, and the intensity will vary depending on the path difference.

 

  • The bright fringes are formed due to constructive interference and dark fringes are formed due to destructive interference.

 

  • The distance to a bright fringe from the central maximum caused by constructive interference is given by,

y=mλLd

Here m is the order of the maxima, λ is the wavelength of the source, L is the distance from the slit to the screen's center point, and d is the slit spacing.
