How does the energy of an electromagnetic wave relate to its frequency and wavelength?

• Higher energy waves have lower frequency and longer wavelengths.

• Higher energy waves have higher frequency and shorter wavelengths.

• Energy is unrelated to frequency or wavelength.

• Lower energy waves have higher frequency and shorter wavelengths.
