Expert Solution
Step 1
  • In a double-slit experiment, light waves are passed through two closely placed slits. This causes interference of the light and forms alternating bright and dark fringes on a screen with a maximum at the center.

 

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

 

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

ym=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.
