The correct equation that relates the energy of electromagnetic radiation to its frequency is:
E = hν
Where:
- E is the energy of the electromagnetic radiation,
- h is Planck's constant (approximately \(6.626 \times 10^{-34} , \text{Js}\)),
- ν (nu) is the frequency of the radiation.
This equation shows that the energy of a photon is directly proportional to its frequency.
