en.wikipedia.org/wiki/Photon_energy

**Photon** energy is the energy carried by a single **photon**. The amount of energy is
directly proportional to the **photon's** electromagnetic **frequency and** inversely
proportional to the **wavelength**. The higher the **photon's frequency**, the higher its
energy. Equivalently, the longer the **photon's wavelength**, the lower its energy.
