The article Waves and energy wave basics provides additional information about transverse and longitudinal waves, including vocabulary. If the wavelength goes down, then the frequency goes up. The relation that we now believe to be correct is that the wavelength of the photon decreases as the energy of the photon increases. The relationship between energy (E), frequency and wavelength can be described with this equation: The energy is simply the photons frequency multiplied by the Planck constant (h). In chemistry and physics, we come across this parameter in a range of calculations, often to do with photons and light. Identify the INCORRECT statement below: 3.
