WebShorter wavelengths have higher energy as they oscillate faster, while larger wavelengths, which oscillate more slowly, have lower energy. To obtain the photon energy, you need to multiply the velocity of the light ‘ c ’ in the vacuum by the Planck constant ‘ h ’ and divide this by the wavelength of the photon ‘ λ ’. WebWe can think of the incident light as a stream of photons with an energy determined by the light frequency. When a photon hits the metal surface, the photon's energy is absorbed by an electron in the metal. The graphic below illustrates the relationship between light …
