What is the maximum wavelength of light capable of ejecting an electron with a velocity of $5.00\times {10}^{5}\text{ m/sec}$ from a surface with a work function of $2.15\times {10}^{-19}\text{ J}$?

Note:

  • $h=6.626\times{10}^{-34}\text{ J s}$
  • $c=3.00\times{10}^{8}\text{ m/s}$
  • ${m}_{e}=9.109\times{10}^{-31}\text{ kg}$
