Sodium metal requires a photon with a minimum energy of 4.41 x10-19 J to emit electrons.
(a) What is the minimum frequency of light necessary to emitelectrons 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 themaximum possible kinetic energy of the emitted electrons?
(d) What is the maximum number of electrons that can be freed by aburst of light whose total energy is 1.00 uJ?
