Sure! Let's go over the calculations for a single-slit diffraction scenario. Can you provide the details of the setup? Specifically, I need:

1. Wavelength ($\lambda$) of the light in meters
2. Slit width ($a$) in meters
3. Distance to the screen ($L$) in meters
4. Order of the fringe ($m$) if you’re looking for a specific one
5. Any measured fringe width for verification

For a single-slit diffraction pattern, the minima are given by:

$a \sin \theta = m \lambda$

where $m = 1, 2, 3, \dots$ (no central maximum).

The approximate fringe width (if small angles apply) is:

$y_m \approx \frac{m \lambda L}{a}$

Let me know your values, and I’ll calculate it again! Also, do you want to compare this with the double-slit result?

Tip:

If you’re measuring fringe distances, ensure your setup avoids parallax errors by looking straight on at the screen!
