Sodium metal requires a photon with a minimum energy of 4.41 x 10-19 J to emit electrons.

(a) What is the minimum frequency of light necessary to emit electrons from sodium via the photoelectric effect?

(b) What is the wavelength of this light?

(c) If sodium is irradicated with light of 439 nm, what is the maximum possible kinetic energy of the emitted electrons?

(d) What is the maximum number of electrons that can be freed by a burst of light whose total energy is 1.00 uJ?
