Problem

Monochromatic light of wavelength 600 nm600\,\text{nm} falls on a metal surface whose work function is 2.0 eV2.0\,\text{eV}. Determine whether photoelectric emission will occur and, if it does, calculate the maximum kinetic energy of the emitted electrons in electron-volts. \newline (Take h=6.63×10−34 J sh=6.63\times10^{-34}\,\text{J s}, c=3.0×108 m s−1c=3.0\times10^{8}\,\text{m s}^{-1}, 1 eV=1.6×10−19 J1\,\text{eV}=1.6\times10^{-19}\,\text{J}.)
