Photon energy is directly proportional to photon frequency. Learn how frequency and wavelength of light are related in this article. >> The greater the average kinetic energy, the higher the temperature >> As temperature increases, the amount of emitted energy (radiation) increases, while the wavelength of peak emission decreases. Problem 6: Two sound notes produced by a tuning fork are traveling at the same speed. The number of complete wavelengths in a given unit of time is called frequency (f). If the wavelength goes down, then the frequency goes up. As the wavelength of a photon increases, its energy decreases. An increase in frequency produces a proportional decrease in the wavelength of light, with a corresponding increase in the energy of the photons that comprise the light. From this relationship, we see that in a medium where vw is constant, the higher the frequency, the smaller the wavelength. d. As the wavelength of a photon increases, its frequency decreases. 1.
