Problem

Consider two different light sources produce photons of light with wavelengths of 225 nm and 650 nm. If these photons are shined onto zinc metal, which has a work function of 350 kJ/mol, which statement is true? (Hint: The work function corresponds to the least amount of energy required to cause an electron to be ejected from a substance).

a. Only the 225 nm photon can cause an electron to be ejected from zinc.

b. Only the 650 nm photon can cause an electron to be ejected from zinc

c. Neither photon can cause an electron to be ejected from zinc

d. Both 225 and 650 nm photons can cause an electron to be ejected from zinc

e. None of the above
