Question

What Is the Work Function Of A Metal?

Answer 1

Work Function Of A Metal

1. A photoelectric effect occurs when a wavelength or frequency of radiation is incident on a metal surface.
2. The work function of a metal is defined as the minimal amount of energy required to simply remove an electron from an atom.
3. The difference between incident energy and the metal's work function equals the kinetic energy of released photoelectrons.
4. An electron requires a specific amount of energy to emit out from the metal's surface.
