Photon Energy-Frequency Calculator — Fórmula
## Photon Energy from Frequency
A photon's energy is directly proportional to its frequency.
### Formula
**E = h f**
- *h* = 6.626 x 10^-34 J s (Planck constant)
- *f* = frequency in Hz
The wavelength is lambda = c / f. Higher frequency (shorter wavelength) means higher energy.

Ejemplo Resuelto
Green light at 500 THz (5e14 Hz).
- E = h f
- E = 6.626e-34 * 5e14
- E = 3.313e-19 J
- E = 3.313e-19 / 1.602e-19 = 2.069 eV
- lambda = 3e8 / 5e14 = 6e-7 m = 600 nm
