Question

Photon energy expressed as?

RankGuru · Accepted Answer

1. **Planck's Law**: The energy ($E$) of a single quantum of electromagnetic radiation (photon) is directly proportional to its frequency ($f$).
2. **Constant**: The constant of proportionality is Planck's constant ($h$).
3. **Formula**: **$E = hf$**.
4. **Waveform**: Using $c = f\lambda$, it can also be written as $E = \frac{hc}{\lambda}$.
