Problem 12 Easy Difficulty

Lithium, beryllium, and mercury have work functions of 2.30 eV, $3.90 \mathrm{eV},$ and 4.50 $\mathrm{eV}$ , respectively. Light with a wavelength of $4.00 \times 10^{2} \mathrm{nm}$ 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 energy for the photoelectrons in each case.

Answer

a. \text { lithium }
b. 0.81 \mathrm{eV}
