Question: lithium beryllium and mercury have work functions of 230 ev...

Question details

Photoelectric Effect Lithium, Beryllium and Mercury have work functions of 2.30 eV, 3.90 eV, and 4.50 eV, respectively. Light with a wavelength of 400 nm is inci- dent on each of these metals. (a) Determine which of these metals exhibit the photoelectric effect for this incident light. Explain your reasoning. (b) ind the maximum kinetic energy of the photoelectrons in each case (where the photoelectric effect occurs).
