(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

The diffraction pattern shown in the figure is produced by passing He-Ne laser light (λ = 632.8 nm) through a single slit and viewing the pattern on a screen 1.58 m behind the slit.

What is the slit width?

2. Relevant equations

a = {(wavelength)D}/(distance of minima)

3. The attempt at a solution

a = {(632.8 x 10^-9)(1.58)}/(.152)

Answer: slit width = 6.577 x 10^-6 which is very wrong.

I feel like my equation is definitely wrong.
