Final answer:
The energy carried by an electromagnetic wave can be represented by the frequency of light.
Step-by-step explanation:
An example of energy carried by an electromagnetic wave is the frequency of light. The energy of a photon is directly related to its frequency, as given by E = hv, where E is the energy, h is Planck's constant, and v is the frequency of the wave. Higher frequency photons carry more energy than lower frequency photons.
