What is the energy change occurring in the atom due to this emission? If the energy of each wavelength is considered to be a discrete packet of energy, a high-frequency wave will deliver more of these packets per unit time than a low-frequency wave. 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). Wavelength and Frequency: Of the various properties of a wave, two of the most important, and common, to work with are wavelength and frequency. b) As wavelength increases, energy increases. Wavelength is described as the distance between a trough to a trough or a crest to a crest. The energy associated with a wave is directly proportional to its frequency. southwest (that is, at 45 degree from directly south and from directly west), vector d2 for 0.50 m due east, vector d3 for 0.60 m at 60 degree north of east. In a wave, the material on which the wave is travelling is moving. Why does wavelength decrease as frequency increases? Sean is a consultant for clients in the pharmaceutical industry and is an associate lecturer at La Trobe University, where unfortunate undergrads are subject to his ramblings on chemistry and pharmacology. The wavelength of the first wave ( 1) = 100 10-3 m = 0.1 m, Frequency of the first wave (f1) = 6 kHz = 6 103 Hz, Frequency of the second wave (f2) = 5.4 kHz = 5.4 103 Hz.
