Question

Work function for a metal will change if

Answer 1

Explanation:

The work function of a metal, Φ, is the minimum amount of energy required to elicit the ejection of a photon. It is typically exhibited in units of eV (electron volts) or J (Joules). ... The kinetic energy of the ejected electron is equivalent to the work function of the metal subtracted from the energy of a fired photon.

Answer 2

The work function of a metal changes if the intensity of the light energy applied over a metal changes.

Explanation:

• Work function is defined as the minimum amount of energy required in the ejection of an electron from the metal.
• The application of light can be used as a source of energy in removing the electrons from the metal surface.
• If the intensity of the light applied is less, the work function will be also less.
