Question

Quizplus · Accepted Answer

The work function is a property of the metal that the light strikes, and is defined as the minimum amount of energy required to remove an electron from the surface of the metal. It depends on the chemical and physical properties of the metal, such as its atomic structure and the strength of the bond between the electrons and the metal ions. The incident wavelength, applied voltage, light intensity, and current can all affect the kinetic energy of the emitted electrons, but not the work function itself.
