Radiation Pressure calculator
Photon pressure on absorbing or perfectly reflecting surfaces.
Category: Photonics
Formula: P_abs = I/c · P_refl = 2I/c
Inputs
| Input | Parameter | Unit | Default |
|---|---|---|---|
| Irradiance I | I | W/m² | 1000 |
| Spot side | A | mm | 1 |
Result with the default inputs
- P (absorber): 3.3356e-6 Pa
- P (reflector): 6.6713e-6 Pa
- Force on A² (refl.): 0.0067 nN
Open it with your own values: put each input in the address as a parameter, for example /calculators/radiation-pressure?I=1000. A unit other than the listed one goes in <parameter>_unit.
