The work function (Φ) for a metal is 5.60×10-19 J. What is the longest wavelength of electromagnetic radiation that can eject an electron from the surface of a piece of the metal?
Homework Answers
(Φ) = h C / 
= h C / Φ
= 6.626 x 10^-34 x 3 x 10^8 / 5.60 x 10^-19
= 3.55 x 10^-7 m
= 355 nm
wavelength = 355 nm

A metal element was used to in coating cathode surface of a phototube. It was studied for its work function by impinging EM radiation with wavelength of 207 nm and measuring its stopping potential as 0.982 eV. What is the longest wavelength of EM radiation required to eject an electron from the cathode surface? 1eV = 1.6022 x 10-19 J? How does stopping potential factor into this equation?
