Photon energy from frequency
Calculate the energy of one photon from its electromagnetic frequency using the exact SI Planck constant.
Method and scope
E = hf, with h = 6.62607015 × 10⁻³⁴ J·s exactly.
Use photon energy from frequency for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Photon frequency — Hz
SOURCE AND LIMITS
Assumptions: Frequency refers to a single photon in vacuum or a linear medium without changing photon frequency.
Limitations: This is energy per photon, not total beam energy.
