Recall the fundamental relationship between the energy (E) of a photon and the frequency (\(\nu\)) of electromagnetic radiation, which is given by the equation:
\[E = h \times \nu\]
where \(h\) is Planck's constant.
Understand that Planck's constant (\(h\)) is a positive constant with a fixed value, so the energy is directly proportional to the frequency.
Analyze the proportionality: as the frequency (\(\nu\)) increases, the energy (E) must also increase because they are multiplied by a positive constant.
Recognize that this means energy and frequency have a direct, linear relationship, so energy does not decrease or remain constant when frequency changes.
Conclude that the correct description of the relationship is: 'Energy increases as frequency increases.'
