Webhave higher frequency,n, and shorter wavelength, l, than light and radio waves. The radiation can be considered as emitted in quanta, photons, each quantum having a well defined energy,hn, where h is a physical constant, Plancks constant, andn is the frequency. The energy of X-ray photons are considerably higher than those of light. WebIn terms of photons, higher amplitude light means more photons hitting the metal surface. This results in more electrons ejected over a given time period. As long as the light frequency is greater than \nu_0 ν 0, increasing the light amplitude will cause the electron current to …
