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

Question

Higher frequency waves have less energy
Lower frequency waves have more energy
Energy is independent of frequency
Higher frequency waves have more energy

Answer 1

Higher frequency waves have more energy.

This relationship is described by the equation \( E = h \cdot f \), where \( E \) is the energy of the photon, \( h \) is Planck's constant, and \( f \) is the frequency of the electromagnetic wave. As the frequency increases, the energy of the wave also increases. Conversely, lower frequency waves correspond to lower energy.
