A Metal Surface Has a Work Function of 1

question 10

Short Answer

A metal surface has a work function of 1.50 eV.Calculate the maximum kinetic energy,in eV,of electrons ejected from this surface by electromagnetic radiation of wavelength 311 nm.
(c = 3.00 × 10⁸ m/s,h = 6.626 × 10^-34 J ∙ s,e = -1.60 × 10^-19 C,1 eV = 1.60 × 10^-19 J)
