Quantized Energy and Photons (Section)
Molybdenum metal must absorb radiation with a minimum frequency of 1.09 × 1015 s-1 before it can eject an electron from its surface via the photoelectric effect. (a) What is the minimum energy needed to eject an electron? (b) What wavelength of radiation will provide a photon of this energy? (c) If molybdenum is irradiated with light of wavelength of 120 nm, what is the maximum possible kinetic energy of the emitted electrons?
