The work function of a metal is 5 eV. What is the kinetic energy of the photoelectron ejected from the metal surfacethe energy of the incident radiation is 62 eV ? (1 eV-1.6 x 101952.) 6.626 × 10-19JC) 1.92 × 10-18J8.01 × 10-19JD)3.92 × 10-19J |

Answer» K.Emax = energy of incident radian - Work function = 6.2 -5 = 1.2 eV = 1.2*(1.6×10^-19) = 1.92 × 10^-19 J |
