Bragg’s Law Calculator

Calculate the diffraction angle using: $$ n\lambda = 2d\sin\theta $$

* Use consistent units for λ and d. Ensure nλ/(2d) ≤ 1.

Step 1: Enter Parameters

e.g., 1

e.g., 500 (enter the same units as d, e.g., nm)

e.g., 200 (same units as λ, e.g., nm)

Bragg’s Law: $$ n\lambda = 2d\sin\theta $$
Rearranged: $$ \theta = \sin^{-1}\left(\frac{n\lambda}{2d}\right) $$
