Lithium, beryllium, and mercury have work functions of 2.30eV,3.90eV, and 4.50eV respectively. Light with a wavelenth of4.00 X 102 nm is incident on each of these metals.
(a.) Which of these metals emit photoelectrons in response to the light?Why?
(b.) Find the maximum kinetic enery for the photoelectrons in each case?
