Compute a photon's relativistic momentum p = h/λ from wavelength, for radiation pressure, Compton scattering and quantum-optics momentum estimates.
光子的相对论动量。
| Item | Formula / Note | Source / Standard |
|---|---|---|
| Photon momentum | p = h/λ = E/c | Compton effect |
| Radiation pressure | P_rad = I/c for absorption | Maxwell theory |
| Reflection | Doubles for perfect reflection | Momentum conservation |
| Optical tweezers | Gradient force from momentum transfer | Ashkin 1986 |
| Compton evidence | Scattering proves photon momentum | Compton 1923 |
| Example | 1 eV photon p ≈5.34×10⁻²⁸ kg·m/s | Unit conversion |
