Question #55759

1. The photoelectric effect is the ejection of electrons by a metal when struck with light of

sufficient energy. If a beam of light with energy = 3.960 eV is applied to a sodium metal

surface (work function = 2.384 eV), what is the maximum kinetic energy of the ejected

electrons? * Ke max; the maximum kinetic energy of the ejected electron

sufficient energy. If a beam of light with energy = 3.960 eV is applied to a sodium metal

surface (work function = 2.384 eV), what is the maximum kinetic energy of the ejected

electrons? * Ke max; the maximum kinetic energy of the ejected electron

Expert's answer

K_{E,max} = hv - φ = 3.960 eV - 2.384 eV = 1.576 eV

Answer: 1.576 eV

Answer: 1.576 eV
