Bragg diffraction

Introduction
Procedure
Results & analysis
The results of the measurement are shown in Figure 1 (above). We can identify clearly six peaks at 12$^{\circ}$, 20$^{\circ}$, 24$^{\circ}$, 31$^{\circ}$, 47$^{\circ}$ and 59$^{\circ}$. Considering that the wavelength of the source used to measure the diffraction is $\lambda=2.85\,\mathrm{cm}$, we obtain the following values for the interplane distance $d$:
| Peak position ($^{\circ}$) | Diffraction order ($n$) | $d$ |
|---|---|---|
| 12 | 1 | 6.12 $\pm$ 0.25 |
| 20 | 1 | 3.77 $\pm$ 0.09 |
| 24 | 1 | 3.17 $\pm$ 0.06 |
| 31 | 1 | 2.50 $\pm$ 0.03 |
| 47 | 2 | 3.53 $\pm$ 0.03 |
| 59 | 2 | 3.01 $\pm$ 0.02 |
