Question

In the photoelectric effect, a packet of light (photon) strikes a metal and gives all of its energy to one electron Shows a photon hitting a metal surface and an electron coming out As long as electron gets enough energy from the photon, it can escape from the metal. Suppose a photon with an energy of 2.90 eV strikes a piece of metal. If the electron that it hits loses 1.19 eV leaving the metal, what is the kinetic energy of the electron once it has broken free of the metal surface? Submit Answer Tries 0/10 Suppose an electron breaks from free from a metal surface with a kinetic energy of 0.340 eV. If it lost 0.560 eV of energy leaving the metal, what was the energy of the photon absorbed? Submit Answer Tries 0/10

Explanation / Answer

energy of photon = energy used in leaving from metal + kinetic energy

2.90 = 1.19 + KE

KE = 1.71 eV

energy of photon = energy used in leaving from metal + kinetic energy

energy of photon = 0.560 + 0.34

energy of photon = 0.90 eV
