Dynamic electric fields are a property of photons. Dynamic electric fields (along with dynamic magnetic fields) are responsible for the transmission of electromagnetic energy, such as visible light.
- Photons are massless particles that carry electromagnetic energy. A photon is a quantum of light.
- The electric fields produced by photons are oscillating, meaning their strength varies between maximum and minimum values over time.
- The frequency of the electric field determines the frequency of the photon. The higher the frequency of the photon, the shorter the wavelength of the photon.
