What to enter
| Input | Meaning and units |
|---|---|
| Photon frequency (Hz) | Enter photon frequency in Hz; use the same basis as the other measurements. |
Understanding your result
Read Photon energy (J) in the units and model stated on this page. The formula energy=6.62607015e-34*frequency defines the relationship; measurement accuracy and model applicability are separate from numerical precision.
Common mistakes
- Mixing input units or changing the physical meaning of a variable without changing the model.
Check your calculation
- Use the worked example as a known reference case, then change one input at a time and check the direction and units of the response.
