Using a 681 nm 681 nm wavelength laser, you form the diffraction pattern of a 1.1 mm 1.1 mm wide slit on a screen. You measure on the screen that the 12 th 12th dark fringe is 8.63 cm 8.63 cm away from the center of the central maximum. How far is the screen located from the slit?

The distance of the screen from the slit is  

Explanation:

       From the question we are told that

              The wavelength of the laser is

               The width of the slit is

                The number of  dark fringe that is being considered  

                The distance to the center of the central maximum is

The distance of the screen from the is mathematically represented as

 Substituting values we have

b

explanation:

what type of charge does it have? negative
