Question
Using a 683 nm wavelength laser, you form the diffraction pattern of a 1.1 mm wide slit on a screen. You measure on the screen that the 13 th dark fringe is 8.57 cm away from the center of the central maximum. How far is the screen located from the slit

Answer:
10.2 m
Explanation:
The position of the dark fringes (destructive interference) formed on a distant screen in the interference pattern produced by diffraction from a single slit are given by the formula:
where
y is the position of the m-th minimum
m is the order of the minimum
D is the distance of the screen from the slit
d is the width of the slit
In this problem we have:
m = 13 is the order of the minimum
Solving for D, we find the distance of the screen from the slit:
