How to use the compton scattering wavelength shift calculator
Find how much an X-ray or gamma photon lengthens in wavelength when it scatters off an electron. Enter scattering angle, incident wavelength in the fields above; the compton wavelength shift, scattered wavelength are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “Compton shift”, “photon scattering angle”, “Compton effect calculator”, “calculate compton scattering wavelength shift”, “find compton wavelength shift”.
Formula
Variables
- th — Scattering angle (°)
- lam0 — Incident wavelength (pm)
Worked example
With scattering angle = 90 °, incident wavelength = 100 pm, the calculator gives compton wavelength shift ≈ 2.42631 pm; scattered wavelength ≈ 102.4263 pm.
Frequently asked questions
What is the compton scattering wavelength shift calculator used for?
Find how much an X-ray or gamma photon lengthens in wavelength when it scatters off an electron. It helps with questions such as “Compton shift”, “photon scattering angle”, “Compton effect calculator”.
What is the formula for the compton scattering wavelength shift calculation?
Compton wavelength shift (pm) = HPLANCK / (ME × CLIGHT) × (1-cos(th)) × 1e12. Scattered wavelength (pm) = lam0+[Compton wavelength shift]. Here th is scattering angle (°), lam0 is incident wavelength (pm).
What inputs do I need for the compton scattering wavelength shift calculator?
You need scattering angle in °, incident wavelength in pm. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the compton scattering wavelength shift calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the compton scattering wavelength shift result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
