Which describes a relationship when calculating the energy of a photon?

Question

The energy of the photon is directly proportional to frequency.
The energy of the photon is inversely proportional to frequency.
As the energy of the photon increases, Planck’s constant increases.
As the energy of the photon increases, Planck’s constant decreases.

Answer 1

The correct statement describing the relationship when calculating the energy of a photon is:

The energy of the photon is directly proportional to frequency.

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 photon. This indicates that as the frequency increases, the energy of the photon also increases.
