Whether 2d sinθ = nλ holds.
1
At a glance:2d·sinθ = nλ; the calculator reports whether the condition holds. Complements bragg-diffraction and diffraction-grating.
Formula
2d·sinθ = nλ.
$$n\lambda = 2d\sin\theta, \quad \theta = \arcsin\frac{n\lambda}{2d}, \quad d = \frac{a}{\sqrt{h^2 + k^2 + l^2}}$$How to Use
- Enter λ, d, order and angle.
- The tool returns sinθ and the check.
Case Studies
λ=1e-10, d=2e-10, n=1
sinθ = 0.25.
FAQ
Max angle?
sinθ ≤ 1 limits possible orders (nλ ≤ 2d).
