Homework Statement
Monochromatic light with wavelength 580nm passes through a single slit 2.60um wide and 2.10m from a screen.
Find the distance between the first- and second-order dark fringes on the screen.
Homework Equations
y=(n*lamda*L)/d
The Attempt at a Solution
y1=580nm*2.1m/2.1um=0.468m
y2=580nm*2.1m*2/2.1um=0.937m
y2-y1=0.468m
I am not sure how to handle the dark fringes in single slit diffraction, so I am not sure where I am going wrong.
Thanks for people's help in advance.
