In an experiment on the photoelectric effect, electrons emerge
from a Sodium surface with
a maximum kinetic energy of 1.90 eV when light shines on the
surface. The work function
of this sample of Sodium is 2.32 eV.
a. What is the wavelength of the incident light?
b. What is the longest wavelength of light that can cause
photoelectron emission
from this surface?
