At a glance:Δλ = λ_c(1−cosθ), λ_c = h/(m_e c) ≈ 2.43 pm. Complements compton-shift and compton-wavelength.
Formula
Δλ = (h/m_e c)(1 − cosθ).
$$\Delta\lambda = \frac{h}{m_e c}(1 - \cos\theta) = \lambda_c (1 - \cos\theta), \quad \lambda_c = 2.426\,\text{pm}$$How to Use
- Enter the scattering angle.
- The tool returns the wavelength shift.
