Calculate Photon Energy using Planck's Constant Calculator that calculate the photon energy using Plancks constant. A photon is characterized by either a wavelength, denoted by λ or equivalently an energy, denoted by E. There is an inverse relationship between the energy of a photon and the wavelength of the light given by the equation. where E is the maximum energy, h is planck's constant and σ is the work function. b) E = (hc/λ) - σ where λ is the wavelength and c is the speed of light in a vacuum ∴ λ = hc/(E+σ) However I'm not given the energy so how am I to calculate λ? Is there another way to calculate E? I looked in my text book but found nothing relevant :( This frequency to wavelength calculator is especially useful for the calculation of the element length of the dipole antennas. Many of our dipole antennas have adjustable element lengths and by entering the frequency of interest this calculator will calculate the wavelength (or element length) corresponding to the required frequency. energy its atoms have. Since atoms in hotter objects have more energy, they can emit photons with more energy than cooler objects can. (When an atom emits a photon the photon energy comes from the atom, so an atom can’t emit a photon with more energy than the atom had.) So hot objects emit high energy photons, or short wavelength light. Since ...
