Electromagnetic radiation can be described by its amplitude (brightness), wavelength, frequency, and period. By the equation E = h ν E=h\nu E=hν , we have seen how the frequency of a light wave is proportional to its energy.

What is the energy of electromagnetic waves?
ENERGY. An electromagnetic wave can also be described in terms of its energy—in units of measure called electron volts (eV). An electron volt is the amount of kinetic energy needed to move an electron through one volt potential.
What is the formula for the energy of A quantum of electromagnetic radiation?
Early Quantum Physics
The energy E of a photon is equal to hv = hc/λ, where v is the frequency of the electromagnetic radiation and λ is its wavelength.
What is E and H in electromagnetic waves?
F = q (E + v × B). The electric displacement D and magnetic intensity H are related to the electric field and magnetic flux density by the constitutive relations: D = ε E, B = µ H.
